Be prepared to be surprised! We will also explore a few interesting facts about these parts! So, without further do , let’s get started!

Human Body Parts That Start With E

Each part of the human body plays a crucial role in the overall machine. Some organs and systems are crucial for survival, while others may seem more dispensable at first glance but play key roles too! Among the many different parts of the human body, the following parts begin with the letter E:

Discussion about the Parts:

• Ear: The ear is one of the essential organs in the human body. It allows us to hear, balance, and change in pressure. The ear divides into three main sections: the Outer Ear, Middle ear, and Inner ear.
• Ear Ossicle: The ear ossicles are three tiny bones in the middle ear: the malleus, incus, and stapes. The first two are also known as the hammer and anvil, and the last is called the stirrup. These bones bridge the eardrum, and inner ear as sound vibrations travel from the eardrum to the cochlea.
• Elbow Region: The elbow is the joint between the upper arm and the forearm. It is composed of three bones: the upper arm bone (humerus), the inner elbow bone (ulna), and the outer elbow bone (radius). With the elbow, the arm can be bent and rotated.
• Epigastric Arteries: Epigastric arteries are two large arteries that arise from the front of the abdominal aorta, just below the diaphragm. They supply blood to the visceral organs in the upper abdomen and the chest and shoulder muscles.
• Ethmoid Air Cells: They’re a bunch of little air-filled spaces in the ethmoid bone, one of the bones that make up the skull. The ethmoid bone lies in the middle of the face, between the eyes, and above the nose.
• Ethmoid Air Cells, Dry Bones: The ethmoid air cells are also known as the “dry bones” because they provide a playground for your nasal bacteria. These bacteria can travel up into your sinuses and cause an infection when you breathe.
• Ethmoid Air Cells, Openings: The ethmoid air cells are a pneumatized paranasal sinus in the ethmoid bone. The openings to the ethmoid air cells reside on the medial wall of the orbit, superior and inferior to the middle meatus and anterior to the lamina papyracea. The ethmoid air cells communicate with the nasal cavity through these openings.
• Ethmoid Bone: The ethmoid bone is a bone in the human body that extends between the eyes and nasal cavity. It has a complex structure and plays an essential role in the function of the nose. The ethmoid bone consists of the cribriform plate and the labyrinth. The cribriform plate is a thin, flat piece of bone that forms the roof of the nasal cavity.
• Expiration: Expiration is drawing air out of the lungs, which involves multiple human body parts. The act of expiration depends on the muscles between the ribs (intercostal muscles) and the abdominal wall muscles (abdominal muscles).
• Extensor Muscles: Extensor muscles are a group of muscles located in the upper body. These muscles enable us to move our arms and legs away from the center of our bodies. The primary function of the extensor muscles is to extend or straighten our joints, such as when we straighten our arms or legs. Extensor muscles are also responsible for keeping our posture upright.
• Extensor Retinaculum: The Extensor Retinaculum is one of the many important ligaments in the human body. This connection between the ulna and radius of the humerus helps stabilize the elbow joint and keeps the tendons in place at the elbow joint. Injuries to this ligament are relatively common, particularly in athletes who put a lot of stress on their elbows. Treatment typically involves rest, ice, and elevation of the affected arm. In severe cases, surgery may be necessary.
• Extra-Ocular Oblique Muscles: Six extra-ocular muscles control the eye’s movement. These muscles are the superior rectus, inferior rectus, medial rectus, lateral rectus, superior oblique, and inferior oblique. The extra-ocular muscles work by changing the shape of the eyeball, which changes the direction of gaze.
• Extra-Ocular Rectus Muscles: The rectus muscles are responsible for moving the eye in three planes. The medial rectus muscle moves the eyes towards each other while muscle contraction pulls them slightly upwards. The lateral rectus muscle moves both eyes away from each other while slightly lowering them.
• Extrinsic Muscles of Hand: There are many muscles in hand, but the extrinsic muscles are the ones that originate from outside of the hand. These muscles include the deltoid, pectoralis major, biceps brachii, and triceps brachii. These muscles work together to move the hand in various directions. The extrinsic muscles of the hand are essential for movements such as grasping, holding, and punching.
• Eye: The eye is one of the essential parts of the human body. It allows us to see the world around us and perceive objects and images. Each part of the eye performs a specific function, which contributes to the complexity of the eye as an organ.
