Dissectible Me 5 minute anatomy

Sciatic nerve

The largest nerve in the body has many spinal nerve roots in the low back that are often the cause of pain in the lower limb. Let's quickly describe the anatomy of this huge nerve.

Atherosclerosis - the artery disease

One of the huge reasons that exercise and a good diet are so important is atherosclerosis. This pathology describes a change to the walls of arteries that can cause narrowing, rupture or blocking of an artery. If this occurs in an artery supplying blood to the heart or the brain this will probably cause death, and is a leading cause of death in western countries.

Skin anatomy

It's the largest organ in the body (or on the body)? You can't live without it, it is an entire system of the body (the integumentary system), it is the major sensory organ, and it gets wrinkly as you get older. Skin!

Epithelium

There are only four tissues that make up the body (epithelial, connective, muscle and nervous). We should talk about epithelia and carcinoma.

Erb's palsy

Erb's palsy is an upper brachial plexus injury and is an example of why learning the anatomy of the brachial plexus is important. How does this palsy present and what has been injured?

Aorta

The aorta is the major artery that runs the length of the torso, has some cool curves, and supplies blood to everything.

Trendelenburg Gait

Gait is complicated, and Trendelenburg gait is an abnormal gait caused by a weakness or paralysis of the gluteus medius and minimus muscles. How does this work? (Or not work)?

Adrenal Glands and Adrenaline

The adrenal glands are vital and the cortex and medulla of each have different functions. Let's talk about their anatomy and what they do.

Sacroiliac (SI) Joint

The sacroiliac joint is a very strong joint that takes the load of the torso from the vertebral column and sends it to the pelvis and lower limbs. It is a synovial joint that allows a little movement and is strongly supported by ligaments. Pain here is often caused by the joint being pulled too far by the large muscles that cross it or that move the pelvis.

Rib Bones

The ribs are a series of 12 curving bones on either side of the torso forming the walls of the thorax and upper abdomen. Let's talk about their parts and how they move.
