Dissectible Me 5 minute anatomy

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.

Pancreas

The pancreas is an organ that most people know about because of its job in producing insulin and managing blood sugar levels. When this doesn't work correctly diabetes develops. It has other endocrine roles and exocrine jobs too, in digestion. Let's talk about where it is in the body and some of the details of the anatomy of this vital organ in 5 minutesish.

Pelvis Bones

The pelvis has two halves (left and right) but each half is also made up of three bones. Let's look at the anatomy of the ilium, ischium and pubis bones and how they link to the back and lower limb.

Nuchal Ligament

The nuchal ligament is in the back of your neck and you can feel it when you flex your neck forwards. What does it do and where does it come from?

The Pudendal Nerve

The pudendal nerve is responsible for sensation from the external genitalia and the perineum, and for motor innervation of the muscles here including the urethral and anal sphincters. It comes from the sacral plexus, so how does it get to the perineum?

Elbow Pain

In this episode, let’s use the common complaint of elbow pain as a vector to explore the anatomy around the elbow.
Terms covered this week: medial & lateral epicondyle. Pronation & supination. Medial epicondylitis aka golfer’s elbow.  Lateral epicondylitis aka tennis elbow. Flexor muscles, specifically flexor digitorum muscles (superficialis & profundus), flexor carpi ulnaris, flexor carpi radialis, palmaris longus & pronator teres. The extensor muscles, mainly the extensor carpi radialis longus & brevis, extensor carpi ulnaris, extensor digitorum and the supinator muscles.

The Cornea

Let’s discuss the clear transparent tissue that sits anterior to the pupil and iris of your eye. Today we will explore the 5 layers of this tissue and link back to their function. There may be more to this area of anatomy than initially meets the eye……😶
Terms covered this week: the cornea, sclera, and progenitor cells. The 5 layers of the cornea are; the epithelium, the Bowmen’s layer (aka the anterior limiting membrane), the stroma, Descemet’s membrane (aka the posterior limiting membrane) and the endothelium layer. The debated sixth layer is also mentioned which is called Dua’s layer.

The Azygos vein

The anatomy of venous drainage of the thoracic wall. What is the azygos venous system? Where is it found? Why is it important & interesting?
Terms covered this week, The azygos, hemiazygos & accessory hemiazygos veins.
