The human body is an amazing machine, and it is made up of many different parts. Each part has a specific function that helps us to live, breathe, and move. Some of the parts of the human body that start with the letter N include the nose, the neck, and the navel. In this blog post, we’ll explore some of these body parts and learn more about them.
Human Body Parts That Start With N
The first one is the nose. The nose helps us smell things, and it also filters out dust and other particles from the air we breathe. Next, we have the neck. The neck is responsible for holding up our head, and it also plays an essential role in swallowing food and liquids. Along with the above, there are plenty of other parts of the body that begin with N:

Discussion about the Parts
- Nails: Nails are one of the essential human body parts. They protect our fingers and toes from injury, help us grip things, and enable us to scratch ourselves when itchy. We probably all take our nails for granted, but they fulfill a vital role in our everyday lives. Nails consist of keratin, a protein that helps keep skin and hair healthy. They grow from the nail bed, the soft tissue beneath the nails.
- Nare: Nare is an ancient Sanskrit word that means “nose.” It’s also the name of a small muscle in the human body. This muscle is responsible for keeping the nostrils open during inhalation. In other words, without the nare, we wouldn’t be able to breathe through our noses!
- Nares, Posterior (Choanae): The Nares, or Posterior (Choanae), are two openings at the back of the nose that allow air to enter the nasal cavity. Each naris has a circular area of cartilage called the ala. The posterior ends of the nasal cavity divide into left and right sections by a partition called the septum.
- Nasal Bone: The nasal bone is a human body part located at the center of the face. It is significant for many facial expressions and helps support the eye’s lens. Additionally, it assists in filtering air breathed in through the nose by providing a surface for mucus to adhere to.
- Nasal Cavity: The nasal cavity is a part of the respiratory system located in the head. It’s responsible for warming and moistening inhaled air and filtering out debris: the mucus that lines the nasal cavity that traps dust, bacteria, and other stuff.
- Nasal Septum: Nasal septum is the cartilage that separates your nostrils and separates your left and right airways. It’s the wall of your nose, and it’s essential for keeping air flowing through your nose evenly. If your septum is crooked or blocked, it can make it harder to breathe through your nose.
- Nasolacrimal Duct: Nasolacrimal ducts are tiny tubes that carry tears from the eye to the nose. Tears are necessary for maintaining the eye’s surface’s health and providing lubrication during blinking. The nasolacrimal ducts help keep the eyes clean and moist by draining excess tears into the nose. It’s up in the upper part of the face, just below the eyes. Each eye has its nasolacrimal duct, which opens into a tiny sac at the base of the nose called a tear lake.
- Navel: A protrusion on the abdomen marks where the umbilical cord attaches to a developing fetus. After birth, the cord cuts, and the navel becomes an empty scar. The shape and size of a person’s belly button can vary significantly from one person to the next. Some people have protruding navels, while others have deeply-indented ones.
- Navicular: Navicular is a small bone in the human body located in the foot. While it may not be the most significant or most noticeable bone, it plays an important role in helping to support the weight of the body and keep us stable when we are walking or standing. Because of its position and function, the navicular gets referred to as the “keystone” of the foot.
- Navicular Bone: The navicular bone is one of the small bones in the foot. It sits below and medial to the anklebone (also known as the talus) and helps form the foot’s arch. The navicular bone also articulates with two other small bones in the foot, called the cuboid and cuneiform bones. The navicular bone is vulnerable to injury because it’s located near the skin’s surface and is relatively thin. A break or fracture of this bone is called a “navicular fracture.”
- Neck: The neck consists of several muscles and bones, including the cervical vertebrae, the hyoid bone, and the sternocleidomastoid muscle. These muscles and bones allow your head to move up and down, side to side and rotate from front to back. The neck is also responsible for supporting your head. This means that it’s essential to keep the neck muscles strong and flexible to maintain good posture and avoid injuries.
- Neck Muscles: Neck muscles are some of the essential muscles in the human body. They support the head and allow us to move it in various directions. Several different neck muscles include the sternocleidomastoid, trapezius, and levator scapulae. Neck muscles can be injured or strained through activity or poor posture. Often, neck pain happens by tension in the neck and shoulders. This gets better with stretches, massages, and ice or heat therapy.
- Neck Veins: The neck veins are a group of veins that run along the sides of the neck. They are responsible for carrying blood from the head and face back to the heart. The jugular vein is the most prominent in the body and runs through the middle of the neck. The other veins in the group include the internal jugular vein, external jugular vein, and dural venous sinuses.
- Neocortex: The neocortex is the brain’s latest and most sophisticated region. It’s responsible for higher cognitive functions such as thinking, abstraction, planning, reasoning, and language. Interestingly, while the neocortex is mainly responsible for our human abilities, other animals also have a neocortex (or something similar), indicating that this part of the brain is not solely responsible for our unique capabilities.
- Nephron: The nephron plays a structural and functional role in the functioning of the kidney. It says that each person has about a million nephrons in each kidney. Nephrons are responsible for filtering blood and producing urine. Each nephron has a glomerulus, a group of capillaries, and a renal tubule. The glomerulus filters the blood, and the renal tubule reabsorbs certain substances from the filtrate before it becomes urine. Nephron function declines with age, contributing to age-related changes in kidney function.
- Nerves: Nerves are essential for human body parts. They are thin, cable-like structures that conduct electrical impulses from the brain and spinal cord to every other part of the body. Touch, pain, and temperature are all sensed by our nerves. They also allow us to move our muscles and organs. Damage to nerves can cause a wide range of problems, including pain, numbness, weakness, and paralysis.
- Nerves of The Upper Extremity: This includes the shoulder, forearm, and hand, which are part of the upper extremity. The upper extremity bones include the humerus, radius, and ulna. Muscles in the upper extremity are responsible for the shoulder, arm, forearm, and hand movement. The upper extremity nerves include the brachial plexus, radial nerve, ulnar nerve, and median nerve.
- Nipple: Nipples come in all shapes and sizes. Some are large and protrude, while others are small and flat. Nipples can also be of different colors – ranging from light pink to dark brown. And while the appearance of nipples may vary from person to person, they all have one common function: to produce milk for newborn infants. Nipples are composed of mammary glands, which grow in lobes around a central nipple duct. The mammary glands produce milk by extracting nutrients from the bloodstream and then secreting them into the ducts.
- Nose: The nose is a human body part that helps us breathe, smell, and taste. It also helps protect the lungs from dirt and other particles. The nose consists of bone, cartilage, and soft tissue. It has two nostrils that open into the nasal cavity. Essentially, it filters and warms the air we breathe before it goes into our lungs.
- Nose Bridge: The bridge of the nose refers to the smooth, scale-like surface between the center of your forehead and the tip of your nose. It houses both nostrils (the openings through which we breathe) and serves as an anchoring point for the muscles that control facial expressions. The bones of the nasal bridge are known as nasal bones, and these bones fuse during fetal development.
- Nose Hole: The human nose consists of two nostrils separate by the septum. It is composed of a narrow band of cartilage and bone that runs down the middle of the nose. Each nostril has its opening in the septum.
- Nostril: Nostrils are two small openings on the sides of your nose. They connect to your nasal cavity, the space behind your nose. The walls of your nostrils have tiny hairs that trap dust and other particles. Nostrils also help you smell things by bringing in air.
- Nuez: The nuez is a part of the human body that helps to regulate blood sugar levels. It does this by releasing insulin in response to sugar intake. When the nuez senses a high sugar level in the bloodstream, it releases insulin to help bring those levels back down. This helps prevent extreme blood sugar fluctuations, which can be harmful to the body over time.
- Nunal: Nunal is a Visayan word that means “a small mass or lump.” In the Philippines, it tends to refer to lumps or tumors found in different parts of the human body. There are many different types of nunal, and each one differs based on its size, location, and other characteristics. Some of the most common nunal include lipomas (fatty lumps), sebaceous cysts (lumps that contain oily material), and wart-like growths.
- Nuque: Nuque is a fancy word for the back of the neck. It’s the area between the base of the skull and the top of the shoulders. Among the most vital organs in the human body, the nuque serves to support and protect the head and spinal cord. There are a lot of different muscles in the nuque, which works together to move your head.
- Nut Sack: A nut sack, also known as a scrotum, is the fleshy pouch that hangs behind the penis in men. The nut sack contains the testes, which produce sperm and testosterone. The nut sack is an important part of the human body, serving several vital functions. First, the testes produce sperm, which is necessary for procreation. Second, the testosterone produced by the testes helps regulate sex drive, muscle mass, and bone density. Third, the nut sack helps keep the testes cool; elevated temperatures can damage or kill sperm cells.
What is the longest body part name?
How to Make Corn Tortillas that Do Not Fall Apart. The longest body part name is the scientific name for the corn tortilla. It is Zea mays subsp. Mays is a variety of maize first domesticated in Mexico about 10,000 years ago. The secret to making perfect corn tortillas is to use fresh masa harina, a flour made from ground dried corn. Masa harina can be found in Latin markets or online.
Once you have the masa harina, mix it with water to form a dough, then start rolling it into balls and flattening it. To cook the tortillas, heat a griddle or skillet over medium-high heat, then cook the tortillas for about 30 seconds per side. That’s it! You now have delicious, fresh corn tortillas that will not fall apart. Enjoy!
