Dissectible Me 5 minute anatomy

Aortic dissection

An aortic dissection occurs when the innermost layer of the aorta tears and blood pushes into the walls of the aorta, separating the layers and causing some very dangerous problems. Let's talk through this process and think about the anatomy that might also be affected.

Anatomical snuff box

The anatomical snuff box describes a clinically useful surface anatomy landmark on the back of the thumb at the wrist, outlined by a triangular set of tendons. In here we find the scaphoid bone and some other structures. I'll try to describe what you can find here on yourself.

Small intestine

There is so much that we could talk about when looking at the anatomy of the small intestine, but if I only had 5 minutes what would I choose as the most important ideas?

Axilla

The axilla is the armpit, and an anatomical space linking the torso with the upper limb. Let's define its borders so we better understand where it is and then we can talk briefly about the structures that we find passing through or residing in there. 

Hyoid bone

The anatomy of this slender U-shaped bone in the neck at the top of the larynx is crucial to the normal functions of the larynx and swallowing, but why?

Parasympathetic nervous system

Squeezing in a little more detail about the parasympathetic nervous system I can talk about all of the cranial nerves that carry parasympathetic neurones, brainstem nuclei, the parasympathetic ganglia of the head and the functions of this division of the nervous system in about 5 minutes.
 

Sympathetic nervous system

What are the most important points about the functional anatomy of the sympathetic nervous system? And what central nervous system structures drive the sympathetic nervous system? In 5ish minutes?

What is the autonomic nervous system?

I'll try to describe what it is and its anatomy in a concise 5 minutes. Ish.

Posterior triangle of the neck

We can use surface anatomy landmarks to define triangles in the neck to help us locate anatomical structures deep to the skin. Within the posterior triangle of the neck we can find the roots of the brachial plexus, the subclavian artery and vein, and most importantly the accessory nerve (CN XI).

Anterior triangle of the neck

The anterior triangle of the neck is a region defined by surface anatomy landmarks that help you locate critical anatomical structures. Let's palpate together!
