The next three pairs, called the false ribs, only attach to the cartilage of the rib above. Rib Anatomy and Structure Your ribs are located in the chest, also called the thoracic cavity. The first seven ribs are called “true ribs.” Neustockimages / Getty Images Instead, they are attached to the costal cartilage of the sternum. The primary job of flat bones is to protect your internal organs. Other flat bones in the human body are found in the pelvis and skull....
Symptoms of these types of arthritis include redness, swelling, stiffness, and pain. Other specific conditions affect the shoulder and hip individually. Hip Conditions Hip dysplasiais a condition where the hip bones do not fully form during development. Ivan Pantic / Getty Images Avascular necrosis often causes pain and hip range of motion limitations. Applying ice and using pain-relieving medications likenon-steroidal anti-inflammatory drugs (NSAIDs)can also help reduce pain. For certain conditions that do not improve with medication and physical therapy, surgery may be needed....
Its the 11th of the 12cranial nervesand is often referred to as CN XI. One part originates in the brain and the other originates in the spine. For this reason, its often called the spinal accessory nerve. Westend61/Getty Images Anatomy All of the nerves in your body stem from either the brain or the spinal cord. They begin with whats called a nerve root. Fibers from multiple nerve roots can combine to form a single nerve....
The amygdala is the part of thebrainprimarily involved in emotion, memory, and the fight-or-flight response. It is one of two almond-shaped cell clusters located near the base of the brain. The amygdalae interpret external stimuli like sights and sounds as potentially dangerous and send that information to the hippocampus. KATERYNA KON / SCIENCE PHOTO LIBRARY / Getty Images This is called anamygdala hijack. Variations can have a significant impact on overall brain functioning....
The ascending colon is the first section. It is also sometimes called the right colon. The ascending colon is the first section of the colon. It receives partially digested food from thesmall intestine. Its held in place by the tissues and membranes that line the abdominal wall. The innermost layer of the ascending colon is called the mucosa. The outermost layer is the serosa, which secretes a fluid to reduce friction from smooth muscle contraction....
Anatomy Your nerves are complex structures. They branch out from their starting points, much like tree limbs. Some of your nerves carry information from your five sensessensory informationto and from your brain. Pornpak Khunatorn/iStock/Getty Images Others enable movement motor functionin your muscles and other moving parts. Some of them provide both sensory and motor function and are thus called mixed nerves. In your head, you have 12 symmetrical pairs ofcranial nerves....
The axillary nerve gets its name from the axilla, which is the medical name for the armpit. You have two, one on each side (as you do with most nerves.) It winds backward and travels down the arm along the posterior humeral circumflex artery. Caiaimage / Sam Edwards / Getty Images This gap provides space for nerves and blood vessels to pass through to the arm. Variations in the axillary nerve appear to be somewhat rare....
The biliary system includes the liver, gallbladder, and pancreas. This article explores the anatomy and function of the biliary system. It also discusses some of the associated conditions and how they are diagnosed and treated. VectorMine / Getty Images Bile Bile is a greenish-brown, thick substance produced in the liver and stored in the gallbladder. The extrahepatic ducts are located outside of the liver and are connected to the liver and gallbladder....
A Muscle That Bends Your Elbow Thebrachialisis a muscle located in your arm near the crook of your elbow. It works closely with yourbicepsbrachiiandbrachioradialismusclesto ensure that your elbow bends appropriately. Injury to the brachialis muscle may cause pain and limit your ability to use your arm normally. It also covers possible injuries and recovery to the brachialis muscle. Anatomy The brachialis muscle originates from the front of yourhumerus, or upper arm bone....
Nerve cells (neurons) communicate with each other to control activity in the brain. Injury to the skull, composed of bone and protecting the brain, also can occur. These conditions can often be managed with medical care. Jollygon / Getty Images The skull surrounds the meninges. The brain regions interact with each other through hormones and nerve stimulation. They include: Function Brain functions often rely on and interact with each other....
It is one of thetarsals, the bones that make up part of the foot and ankle. The calcaneus strikes the ground with every footfall when running or walking. Anatomy The calcaneus is one of seven tarsal bones that make up the foot. Javier Snchez Mingorance / EyeEm / Getty Images All of the tarsals are considered short bones. The calcaneus is the largest of all the tarsals and the largest bone in the foot....
There are seven bones, each called a cervical vertebra, that are stacked upon one another. Atypical Vertebrae The atypical vertebrae are cervical level one and two (C1 and C2). Cervical one is also called the atlas, as it supports the weight of your skull. Both the atlas and axis are small, flat vertebrae. The atlas at cervical level one is a flat, ring-shaped vertebra. It does not have a vertebral body....
It connects smoothly to thesclera(the white part of the eye). The cornea refracts light through thelensbelow it, which allows the eye to process images. Injuries to the cornea can impair a persons vision. PeopleImages / Getty Images The cornea sits above theirisand the lens. The degree of curvature of the cornea greatly affects its ability to refract light. Minor abrasions that affect only the epithelial layer usually heal themselves within 24 hours....
