What comes to mind when you think of body parts that start with e? You may have thought about the elbow, ear, eye, or even enzyme. What if I told you there are more than just these? There is also an Epiglottis, entrails, exoskeleton, esophagus, Endodermis, and more…
This blog post is about all the different human bodies beginning with e. There are a lot of them and they can be really fun to talk about so if you want to learn more and have some laughs this is the perfect article for you!
Some List of Human Body Parts That Start With E
There are many different human body parts that start with the letter E. Some of these include the ear, elbow, and eye. The human body is a complex machine, but it can be broken down into simple components. We’re going to look at some of those components today!
- Eye socket
- Ear lobe
- Eustachian Tube
- External ear
- Ear ossicle
- Extensor Muscle
- Exocrine Gland
- Endocrine System
Top Most Human Body Beginning With The Letter E
Every letter of the alphabet has a special body part that starts with it. In the previous article, we’ve shown parts of the body that start with D. Today, we’re going to talk about the parts of the body that start with e!
Here, we discuss the parts as well as the function of the topmost human body parts beginning with e.
The eyes are the sensory organs of the human body parts. In humans, two eyes capture light from a wide field of view, and light from near objects passes to the brain through the eyeballs.
The eyes, or the ball and socket of the eye, are composed of many small muscles which reflexively correspond to bodily motions.
When something changes in your field of sight, such as a change in depth sensation when you close one eye and look with the other, these muscles will contract or relax accordingly so that your two eyes remain at their normal distance.
- The eyes are an organ that detects light.
- They generate nerve signals, which are sent to the brain for processing into meaningful images.
- The function of the eye is to send electrical signals to the brain for many different body parts to start to process them.
- It does this by focusing on the light which bounces off objects and back onto the retina, a sensory membrane that lines the inside of the eyeball.
- After being processed, these signals are passed through pathways leading from either side of your brain until they eventually meet at the thalamus where they form memories.
The ear is part of the body’s system that conducts sound waves through it. Sound, in general, enters the ear canal and strikes the eardrum or tympanic membrane. The middle ear bones transmit vibrations of sound waves onto fluid in the inner ear which contains receptors for detecting static pressure changes in air particles called hair cells.
And which are sensitive to these changes when they are vibrated by air pressure differences caused by sounds reaching them from all directions.
Once responded to by these cells, auditory signals are sent on farther into parts of the inner brain for further processing and interpretation – beginning at what is commonly referred to as “the hearing center” located on either one side
- The function of the ear is to receive and conduct sound, as well as to detect it.
- And measure pressure changes in the air.
- Another fundamental function of the ear is to maintain balance.
- Balance in most animals is maintained through three semicircular canals in the inner ear, which help control reflexes that keep us upright.
The epidermis is the outermost layer of skin, and it provides a barrier of protection for your body. The top layers of the epidermis are constantly losing cells and being replaced by new cell growths.
The uppermost part of this layer is called the stratum corneum or horny layer, because it’s made up mainly of the formic acid in keratin that gets dissolved, which imparts an appearance that resembles old leather–hence its nickname!
This is where you find the large number of flat cells glued together through desmosomes, with their cytoplasm filled with both amorphous and crystalline proteins that confer shape on them all.
- It provides a tough surface to protect against abrasion and infection.
- This layer also includes hair follicles, sweat glands, and sebaceous glands, which produce fluids that lubricate and protect the skin from water loss.
- Proteins of the Epidermis hold melanin ( pigment), which gives skin its coloration variation.
- The sensory nerve which is endings here is called Meissner’s corpuscles for touch sensations here and Merkel’s fixed-touch receptors for pressure sensations here.
- Keratins form intermediate filaments (which provide structural integrity for tissue) to give strength and elasticity to the epidermal layers.
Enzymes are proteins that catalyze biochemical reactions in the body. It is thought that without enzymes, life would not exist. Enzymes require three things to work: a substrate, an enzyme, and an electron donor.
The substrate is the substance acted upon by the enzyme; for example, sucrose could be acted on by amylase to produce glucose and fructose.
Without the produced glucose and fructose there would be no energy available to sustain life which would lead us to death.
The enzyme is what stimulates these reactions because they alter the structure of molecules so that substrates can break down easily or form other substances easily; we can think of them as kitchen aids in this sense because they come in handy when we need something done quickly
- Enzymes speed up chemical reactions and help maintain important balances within them.
- The major classes of enzymes include those that make molecules, and those that break molecular bonds to cut pieces from massive substances such as starches or glucose.
- Enzymes facilitate chemical reactions in the liver, brain, kidneys, and all other organs in the body.
Exocrine Glands are essential for life as they produce a variety of substances to be excreted from the body. These substances include sweat from piloerector muscles under the arms and on the soles of feet.
A secretion that contains protective providing antibodies or other immune reactions necessary for bodily function, secretions that contain digestive enzymes intended to break down food into nutrients required for cellular metabolism, and absorption. There are exocrine glands throughout our bodies including those in our noses as well as skin tissues.
- The function of the Exocrine Gland is to secrete substances.
- The substances that are secreted by the exocrine glands include sweat, hydrochloric acid, glutamine synthetase, extracellular fluid proteins, and so on.
- One of the Exocrine Glands the Lacrimal Glands produces tears.
- Sebaceous Glands produce oil and given glands perform a vital function in regulating skin pH and generating vitamin D.
- The texture and consistency of these substances also contribute to our sense of touch and taste through what we feel when we grasp an object or put something into our mouth.
We have compiled a list of all the human bodies starting with the letter E. You will be surprised by how many there are! Have fun learning about them.
There are so many different types of body parts out there, but they all contain these amazing organs. We hope this list has helped you learn more about your own body and maybe even some new things about others’ bodies too! Let us know what other body parts should be added to our list in the comments below.
