Welcome to Dissectible Me. Human anatomy in 5-minute chunks.
In this series, we will cover everything from introductions to bodily systems, to some very focused but fascinating nuggets of anatomy knowledge. One rule, it must be covered in 5 minutes only! So join us as we set the timer and rattle through some human anatomy.

How are the tonsils associated with the cerebellum? How can they be herniated and what does this mean? What is coning? Why is this an important sign? I'll explain.
In 5 minutes, what is the anatomy of the cerebellum and what does it do? Why does it have 80% of all of the neurones of the brain? Why does it look like a little brain?
The spermatic cord carries all the things the testis needs to and from the torso. What is the spermatic cord made of, what are its layers, where do these layers come from, and what are all the things inside the spermatic cord?
How can understanding the embryology of the gastrointestinal tract as foregut, midgut and hindgut help us understand the blood supply and venous drainage of the adult GI tract?
"Soma" means "of the body" so what is the somatic nervous system? How is this dividing up of the nervous system useful? I'll try to describe this neuroanatomy concept in 5 minutes.
The ovarian artery branches from the aorta and supplies blood to the ovary. The uterine artery branches from the internal iliac artery and supplies blood to the uterus. But they link, and in doing so provide a collateral circulation route between the abdominal aorta and pelvic internal iliac artery. Let's discuss.
What is the anatomy behind Trendelenburg gait? Why does the hip drop? Which hip drops? Which side is the weakness on? What might cause this? I'll try to describe this clearly in 5 minutes.
A common request is for me to summarise the nerves of the lower limb and how they innervate the muscles. If we think about the parts of the lower limb (thigh, leg and foot) and their compartments we can link each nerve to each compartment and then easily remember every nerve that innervates every muscle. Well, that's the theory.
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.
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.
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?
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.
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?
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.
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?
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).
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!
The lumbosacral plexus is the anatomy of the low back and pelvis that forms the major nerves of the lower abdomen, pelvis and lower limb. It is not as susceptible to injury as the brachial plexus so clinically we understand the anatomy of this plexus a little differently, but it is important to be able to recall the spinal nerve roots of the major nerves here and the functions that will be lost if injured.
