The enteric nervous system describes the nerves of the gastrointestinal tract that autonomously regulate much of its function. Sometimes called the second brain it is a complex network of sensory inputs linked to motor outputs organised into two major plexuses running the entire length of the gut.

The phrenic nerve is well known for its role in innervating the diaphragm and its roots in the C3, 4 and 5 spinal nerves. It also innervates the pericardium, is implicated in the runner's stitch pain and can be responsible for pain in the shoulder.

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.

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.

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!

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 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?

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

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)?

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.
