Wow 😱 Look at the detail! External carotid arteries and its branches which were derived from the carotid artery! πŸ’‰ .

Patient admitted with both his bones broken in his right forearm! 😷 Patient presented with a simple transverse fractures in both the radius and ulna bones! 😱 Scan was done through X-ray for detailed bone scans! .
.
During a surgical procedure to fix a fracture, the bone fragments are first repositioned (reduced) into their normal alignment. They are held together with special implants, such as plates, screws, nails and wires.
.
.
Internal fixation allows shorter hospital stays, enables patients to return to function earlier, and reduces the incidence of nonunion (improper healing) and malunion (healing in improper position) of broken bones.
.
.
The implants used for internal fixation are made from stainless steel and titanium, which are durable and strong. If a joint is to be replaced, rather than fixed, these implants can also be made of cobalt and chrome. Implants are compatible with the body and rarely cause an allergic reaction.

A proud mother from Pittsburgh Pennsylvania told her birth story! A heart warming miracle, born in the car at 29 weeks. How amazing is life πŸ™ŒπŸ» This is her story β™₯️ The human body is truly an amazing πŸ‘ŒπŸΌ. .

"On the 5th of August 2017 at about 10am I started having contractions. I was only 29 weeks and 4 days so I just figured they were Braxton hicks and decided to wait it out. After about 45 minutes of consistent contractions that were increasing in intensity I decided I should probably go in. I there in some clothes. Grabbed my daughter some clothes, her my fiance And I left for the hospital. I dropped my daughter to her God mommy Nicole And headed to the hospital. Well the contractions continued to get closer together and more intense and before I knew it I knew it was time to push. I called 911 because I was so scared. They couldn't understand me between the screams with contractions. So I handed the phone to my fiance. I pulled my pants off and reached down, sure enough his head was right there. I pushed one time and my miracle baby was here. When I looked down I realized he was still completely wrapped in the amniotic sac. The dispatcher told us to pull over. But I knew we would make it to the hospital before they would make it to us. So I told Ean to keep driving. I was so scared. My Fiance was so calm driving and on the phone with 911. At first the baby was still and all I could do was pray he would be okay. And then I rubbed his face with my thumb and he pulled his little hands and feet up to his face as if he understood my prayers and wanted to reassure us he was okay. About 7 minutes passed that I held this miracle baby in my hands until we made it to the hospital. A familiar face came running out and grabbed my baby. He was born an caul. This happens 1 in every 80,000 births. Usually during c-section. He was 3lb 1oz. He doing wonderful all things considered all that he went through I know he's going to be an awesome little man! ❀ he is truly a miracle baby. We are so blessed to be his parents πŸ™πŸ»"

The human heart is one of my favorite organs to study! ❀️ .
.
In humans, the heart is roughly the size of a large fist and weighs between about 10 to 12 ounces (280 to 340 grams) in men and 8 to 10 ounces (230 to 280 grams) in women. .
.
The human heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes.

How do we hear? πŸ€” The mechanism is actually pretty cool; relying on the smallest bones in the body! Aka our auditory ossicles: Malleus, Incus, and the Stapes! .
.
Hearing starts with the outer ear. When a sound is made outside the outer ear, the sound waves, or vibrations, travel down the external auditory canal and strike the eardrum (tympanic membrane). The eardrum vibrates. The vibrations are then passed to three tiny bones in the middle ear called the ossicles. The ossicles amplify the sound and send the sound waves to the inner ear and into the fluid-filled hearing organ (cochlea).
.
Once the sound waves reach the inner ear, they are converted into electrical impulses, which the auditory nerve sends to the brain. The brain then translates these electrical impulses as sound. 😱

Stress can kill brain cells and even reduce the size of the brain. Chronic stress has a shrinking effect on the prefrontal cortex, the area of the brain responsible for memory and learning.😱
.
.
When chronic stress is experienced, the body makes more cortisol than it has a chance to release. This is when cortisol and stress can lead to trouble. High levels of cortisol can wear down the brain’s ability to function properly. According to several studies, chronic stress impairs brain function in multiple ways. It can disrupt synapse regulation, resulting in the loss of sociability and the avoidance of interactions with others.
.
.
While stress can shrink the prefrontal cortex, it can increase the size of the amygdala, which can make the brain more receptive to stress. Cortisol is believed to create a domino effect that hard-wires pathways between the hippocampus and amygdala in a way that might create a vicious cycle by creating a brain that becomes predisposed to be in a constant state of fight-or-flight.

Healthy lungs vs a Smokers lungs! 😱The caption below may shock you because even if you stop smoking the discoloration may still remain! .
.
As soon as you inhale a puff of cigarette smoke your body is alerted to the fact that toxic particles have invaded. Inflammatory cells rush to the scene. One type of white blood cell called macrophages may be thought of as the "garbage trucks" of our immune systems. Macrophages essentially "eat" the nasty brown-black particles in cigarette smoke in a process called phagocytosis. Since these particles could be damaging even to macrophages, they are walled off in tiny vesicles and stored as toxic waste.And there they sit.
.
.
As more and more macrophages containing debris build up in the lungs and lymph nodes within the chest, the darker the lungs appear.
.
.
You may be wondering if the brown and black color ever goes away. After all, macrophages don't live forever. When a macrophage dies, and the vesicles of cigarette waste are released, younger macrophages rush to the scene and ingest the particles. This process can occur over and over during a person's life. This is not to say that healing doesn't take place when someone quits smoking. It does. But the discoloration in the lungs MAY REMAIN!!

Hi everyone! My name is Sofia @sofia_etc_ and I'm a second year medical student at Yale School of Medicine. I love talking about the application process, student life, as well as fashion and beauty on my insta page and blog! Follow along with me on Insta for more on med school life!

Water content varies in different body organs and tissues, from as little as 8 percent in the teeth to as much as 85 percent in the brain. Make sure you drink enough water daily since it's vital to your health and overall well being!πŸ˜‹πŸ˜ŒπŸ’ͺ🏼 .
.
Human beings are mostly water, ranging from about 75 percent of body mass in infants to about 50–60 percent in adult men and women, to as low as 45 percent in old age. The percent of body water changes with development, because the proportions of the body given over to each organ and to muscles, fat, bone, and other tissues change from infancy to adulthood. Your brain and kidneys have the highest proportions of water, which composes 80–85 percent of their masses.

Try this on yourself and you'll be surprised 😌 Learning anatomy the right way πŸ™ŒπŸΌ

The cardiopulmonary system! 😱 Showing the lungs and it's millions of alveoli! The red color depicts oxygenated blood, and the blue depicts deoxygenated blood!

Scanning electron microscope (SEM) of the spinal cord! 😱 The middle contains the cell bodies of the neurons also known as the grey matter (red). The peripheral contains white matter which are the axons of the neurons (yellow) . The white matter is given its name due to the axons being wrapped in myelin sheath which resembles a white appearance! At the very peripheral is the meningeal layer (3 layers: Dura, Arachnoid, and Pia) protecting the spinal cord (white)!
