The Circle of Willis

Continuing with arterial circulation let's explore the cerebral arterial circle or circulus arteriosus, more commonly known as the Circle of Willis. Simply put the blood supply to the brain. 
Today we discuss the arteries that make up the infamous circle. The internal carotid, anterior, middle, and posterior cerebral arteries or the ACA, MCA, and PCA. We also give a nod to the brain's vertebrobasilar system and the cerebellar arteries (AICA & PICA) Finally, we explore the concept of our cerebral anastomotic circulation that safeguards us from ischemia. 
Have a go at listening to the podcast whilst looking at a labelled image of the Circle of Willis.   

Major arteries

Listening to this episode will not be in vain, because we are going to discuss your arteries......😐 
Today we talk about the major arteries that course around the human body. Identifying where one artery begins and the other ends. We also explore some of their major branches, aiming to provide a solid introduction to your arterial system and in doing so revising blood supply. 
 

The Cardiac conduction system

This week is "electric"! Would your heart really continue beating if it were suddenly torn from your body? What is a cardiac arrhythmia? And why on earth are there so many abbreviations used in cardiology? With the exception of the last one, the answers can be found this week as we explore the conduction system of the heart.
Terms we discuss are; The Sinoatrial (SA) node, Atrioventricular (AV) node, Bundle of His, left and right bundle branches, and the Purkinje fibres. Now you see why we abbreviate..... catchy!

Anatomy of the Heart

This week we will get to the very heart of human anatomy.....literally we are talking about the heart.
We will discuss the basics of the organ, its chambers, the coronary vessels, and again link structure to function. 
 

Our Top 5+ Favourite Anatomical terms

In today's episode, we circumnavigate the Islets of Langerhans to the Foramen of Magendie. We encounter the gluttonous inducing Ghrelin and search for the cryptic splenunculus. No, this is not a fantasy novel. We are instead talking about the wonderful world of anatomical terminology. So fasten your gubernacula and let's discuss our favourite anatomical terms. 

The Anatomical position

Join us this week where we travel back in time to our anatomical predecessors and review their justification for the creation of the universal 'anatomical position'. We will also discuss the simple anatomical descriptors that are the very foundation for anatomical study. 
What is the anatomical position.......? Think Da Vinci's Vitruvian man with less enthusiasm and 4 fewer limbs. 

The Female Reproductive system

This week we introduce the female reproductive system. 
In this podcast, we discuss its functions and the anatomy of the external vs internal genitalia.
 
 

The Male Reproductive system

In today's episode, we tackle the 'male' reproductive system. The penultimate episode from our series introducing human anatomy systems. 
Terms covered in this podcast include; The testes vs testis. Sertoli, Leydig and spermatagonia cells. The rete testis, epididymis and the ductus or vas deferens. Seminal vesicles, prostate, and finally the erectile tissues of the corpus cavernosum and spongiosum. 
 

The Immune system

A perfect follow-on from the lymphatic system, today we introduce the immune system and the anatomy thereof...
Can you point to the organs of your immune system? If not, listen in. 
 
 
 

The Lymphatic system

This week we tackle the lymphatic system.
The lymphatic vessels, lymph, chyle, and lymph nodes. We will also introduce the adjunct lymphoid tissues & organs.
Much more on these in the future episodes.
