The body parts that start with L are all essential for the proper functioning of the human body. Without them, we would quickly become sick and would not be able to live for very long. A person should know about the body, especially the different parts that make it up, from an early age. In this blog post, we’ll be discussing some of the human body parts that start with L.
Human Body Parts That Start With L
The largest organ in the body – is the liver. It is responsible for filtering toxins out of the blood and helping to digest food. The following body part is the lungs. The lungs are responsible for exchanging carbon dioxide and oxygen in the blood. The following parts of the human body start with L:
|Liver, Left Lobe
|Lesser Sac (Omental Bursa)
|Liver, Right Lobe
|Lateral Palpebral Ligament
|Levator Ani Muscle
|Long (Greater) Saphenous Vein
|Lateral Rectus Muscle
|Levator Palpebrae Superioris Muscle
Discussion about the Parts
- Laryngeal Muscles: There are three pairs of laryngeal muscles in the human body, and they play an essential role in controlling the voice box. The intrinsic laryngeal muscles are responsible for opening and closing the vocal cords, while the extrinsic laryngeal muscles help move the vocal cords. Thyroarytenoid, cricothyroid, and posterior cricoarytenoid muscles are intrinsic laryngeal muscles. In addition to opening the vocal cords, the thyroarytenoid muscle helps to tense them. The posterior cricoarytenoid muscle helps to close the vocal cords.
- Larynx: The larynx is a cartilaginous organ in the neck that houses the vocal cords. It is responsible for phonation, or the production of sound by the vocal cords. The larynx consists of several cartilages: the thyroid, cricoid, and epiglottic cartilages.
- Lateral Palpebral Ligament: The lateral palpebral ligament is a thin, narrow band of fibrous tissue that connects the outer rim of the eye socket (orbit) to the edge of the eyelid. It helps to keep the eyeball in place and maintains its position in the rotation. The lateral palpebral ligament is also known as the outer canthal tendon or the canthal tendon.
- Lateral Rectus Muscle: It’s a muscle in the human body. As one of six muscles responsible for the eye’s movement horizontally, this muscle is responsible for moving the eye horizontally. The abducens nerve gets power from the lateral rectus muscle, which originates in the brainstem.
- Lateral Ventricles: The lateral ventricles are two C-shaped cavities located in the cerebrum, one on each side of the brain. Each ventricle fills with cerebrospinal fluid (CSF), a clear liquid that surrounds and cushions the brain and spinal cord. The interventricular foramen connects the lateral ventricles to the third ventricle.
- Left Atrium: The left atrium is one of the heart’s four chambers. Pumps blood from the left ventricle to the rest of the body. The left atrium is a thin-walled, cone-shaped chamber about 2.5 inches wide and 1 inch deep. It lies superior to (above) the left ventricle and posterior (towards the back) to the pulmonary veins.
- Left Ventricle: The left ventricle of a person’s heart is one of the heart’s four chambers. It is located on the left side of the heart and pumps oxygenated blood to the rest of the body. There are thicker walls in the left ventricle, making it more efficient at pumping blood. The left ventricle’s job is crucial to keeping the body alive and functioning properly.
- Leg: The leg is essentially a long bone that runs from the hip to the ankle. It consists of the upper leg (thigh) and the lower leg (calf). The upper leg contains the femur – the longest and strongest bone in the human body. The lower leg includes those cute little bones called the tibia and fibula. It has 29 bones – the femur (thighbone), tibia (shinbone), fibula (outer bone of the lower leg), and patella (kneecap).
- Lesser Sac (Omental Bursa): The lesser sac, or omental bursa, is a cul-de-sac located behind the stomach. It is separated from the greater sac by the omentum. The omental bursa contains a thin layer of tissue that secretes a small amount of fluid. This fluid helps to lubricate the organs and tissues in the lesser sac.
- Levator Ani Muscle: The levator ani is a thin, triangular muscle that lies deep to the perineal membrane and superficial to the anal sphincter. It has two parts – the pubococcygeus (PC) and iliococcygeus (IC), which originate from different parts of the pelvis. The PC arises from the pubis, while the IC arises from the coccyx.
- Levator Palpebrae Superioris Muscle: The levator palpebrae superioris muscle is a human body part that serves an essential function in the anatomy of the eye. This muscle is responsible for elevating the upper eyelid and plays a vital role in mastication (chewing) and vision. The levator palpebrae superioris gets its nerve supply from the third cranial nerve (oculomotor nerve), and its blood supply comes from the superior and inferior ophthalmic veins.
- Lingual Nerve: The lingual nerve is a branch of the mandibular nerve, a branch of the trigeminal nerve. As the largest cranial nerve, the trigeminal nerve supplies sensation to most of the head, including the face, scalp, and teeth.
- Lip: Lips are a sensitive body part that can be injured easily. It is also essential to the ability to speak that lips are in good health. In fact, there are several layers of the lip, including the skin, muscle, and fat. It’s called the epidermis. The next layer is the dermis, which contains blood vessels, hair follicles, and sweat glands. The deepest layer is the subcutaneous tissue, containing fat cells and connective tissue.
- Liver: In the body of every living organism, the liver plays an essential role. It is responsible for many vital functions, including detoxification, energy production, and protein synthesis.
- Liver, Left Lobe: The liver, Left Lobe is a human body part located on the left side of the body. It is responsible for many functions, including filtering blood and producing bile. The liver is a large organ and has many different parts. The left lobe is one of these parts. It is important to maintain a healthy lifestyle to keep your liver functioning properly.
- Liver, Right Lobe: This part of the liver seems to be the most significant. You can find it on the right side of the abdomen, beneath the ribcage. The right lobe gets its name because it’s on the right side of the body. The right lobe contains two hepatic veins which drain blood from the liver. This vein joins the portal vein, which carries blood from the liver to other body parts.
- Long (Greater) Saphenous Vein: It’s a long vein that runs from the inner ankle to the groin. This is one of two superficial veins in the lower extremity and the short saphenous vein. The LSV is the most prominent vein in the body and carries up to 80% of the blood from the leg.
- Lumbar Vertebra: The lumbar vertebra are the five largest bones in the spinal column and make up the lower back. They are responsible for supporting the upper body’s weight and play a role in movement and balance. The lumbar vertebra is attached to the pelvis by strong ligaments, and together they form the lumbosacral joint.
- Lungs: Lungs are a pair of spongy, cone-shaped organs that reside on either side of the chest. They are essential for breathing, as they take in oxygen from the air and expel carbon dioxide. Each lung consists of smaller units called lobes, and these split into even smaller structures called alveoli. It is here that gas exchange Between the lungs and bloodstream takes place.
Body parts that start with y and z
Yolk: The yolk is the yellow part of an egg. It is located in the center of the egg and contains most of the egg’s nutrients. It is made up of a thick, nutrient-rich fluid surrounded by two thin membranes. The yolk is a great source of protein, fat, vitamins, and minerals. Zygomatic Bone: The zygomatic bone is a facial bone located in the middle of the face, just below the eyes. It is one of the fourteen bones that make up the human skull. It is an important facial feature, as it helps to form the shape of the cheeks. The zygomatic bone is also important for the attachment of several muscles of facial expression.
