Nerves of the Hand

This week we cover the nerves of the hand. The major motor components & the sensory distribution of each of the nerves that meander into the distal extremity of the upper limb. 
Terms covered in this episode are the median, radial & ulnar nerves. The flexor retinaculum. The thenar eminence & the lumbricals. 

The Atlas & Axis (C1 & C2)

Adorning the top of your spine are two unique vertebrae. Arguably the most important of the lot. Your Atlas & Axis or C1 & C2. In this episode, we explore greek inspired etymology, vertebral osteology & investigate why exactly cervical spinal injuries are so dangerous. By the end of this episode, you should be able to look through the 33 spinal bones all jumbled up & easily pick these two from the bunch. 
Terms covered this week; Atlas & axis. Spinous & transverse processes. Vertebral and transverse foramen. Vertebral body, lateral mass & articular facets. 

The Pineal gland

A fascinating topic this week, the pineal gland. The neuroendocrine structure that releases melatonin and helps regulate sleep cycles. Also, a structure that throughout history people have tried to assign all sorts of unusual functions. Join us this week as we try to unravel fact from fiction whilst covering location, function, and a smidge of clinical relevance.
Terms covered this week are the pineal gland, melatonin, pineal or parietal eye. Circadian rhythm, diurnal & sleep hygiene.  

The Carpal bones

In this episode let’s take a glance at some of the trickiest bones to identify, the bones of the carpus or wrist. More commonly known as the carpal bones.
Terms covered this week. The wrist movements of flexion, extension, ulnar & radial deviation. The carpal bones; trapezium, trapezoid, capitate, hamate, pisiform, triquetrum, lunate & scaphoid. The anatomical snuff box & avascular necrosis.

The Cardiac veins

When it comes to the heart and its blood supply the coronary arteries take most of the limelight. But where does the deoxygenated blood go after supplying the muscle of the heart? How does it return to the circulatory system? In short, it travels through the cardiac veins our focus for this week's podcast. Names, locations and their anatomy. 
Terms covered this week; The great, the middle and the small cardiac veins. The coronary sinus.

The Brainstem (An Introduction)

This week let's take a first pass at covering some brainstem anatomy. Let's discuss the three subsections, the broad functions these have, and point out some of the fascinating features this vital area of the brain houses.
Terms covered this week, The midbrain, the pons and the medulla oblongata. The cerebral and cerebellar peduncles. The corpora quadragemina, which itself is made up of the superior and inferior colliculi. The red nucleus, the substantia nigra and the reticular formation. The medullary pyramids and lots of cranial nerve nuclei. 

The Pericardium

Today let’s discuss the membranous layers of tissue that house and protect the heart. What they are, where they are, function, innervation, importance, and a smidge of clinical relevance to finish.  
Terms covered this week. Layers of the heart; endocardium, myocardium & epicardium. The two layers of the pericardium; the serous pericardium (itself divided into visceral & parietal) & the fibrous pericardium. The pericardial cavity. Phrenic nerves & cardiac tamponade.

Teeth (The basics)

In this episode let’s take a bite out of some dental anatomy, by covering the basics of the tooth. Let’s uncover some details of the organic living rocks that inhabit our jaws, made up of four tissue types with a rich neurovascular supply.
Terms discussed in today’s episode are gingiva, the crown & the root of a tooth. The four tissues are enamel, cementum, dentin & pulp. The gomphosis joint is formed by the periodontal ligaments & finishing off we discuss the neurovascular supply of the superior & inferior alveolar nerves, arteries & veins.

Coronary arteries

The tissue and muscle of the heart need a good blood supply. Enter the coronary arteries. A left and a right but also some other major branches to know about.
Terms, or arteries covered this week; The aorta. The right coronary artery & the posterior descending artery (PDA). The left coronary artery, circumflex artery & anterior interventricular artery aka left anterior descending artery (LAD).

The Shoulder

In this episode, we explore the osteology of the shoulder. The bones, joints & mobility vs stability.
Terms covered in this episode; The bones of the humerus, clavicle and scapular. The articulations of the glenohumeral joint, the acromioclavicular joint and the sternoclavicular joint. Finally the bony projections of the coracoid process, the acromion and the spine of the scapular.
