Dissectible Me 5 minute anatomy

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.

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?
