    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.

    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.

    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.

    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).

    Lumbosacral plexus

    Play Episode Listen Later Feb 14, 2025 6:29


    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.

    Upper and lower motor neurones

    Play Episode Listen Later Feb 7, 2025 7:25


    Understanding the anatomy of upper and lower motor neurones can be very useful when trying to use the results of an examination, signs and symptoms to diagnose the location of a neurological lesion. 

    Spinal tracts neuroanatomy

    Play Episode Listen Later Jan 31, 2025 5:58


    Spinal tracts are bundles of neuronal axons that run through the spinal cord and brainstem. If we think about how neurones work, how they are bundled together with similar functions, which direction the action potentials are running in and the names of these tracts, we can remember what they all do.

    Referred pain

    Play Episode Listen Later Jan 24, 2025 5:13


    Referred pain is felt at a different location in the body from the site that is causing the pain. There seems to be an anatomical reason for this and understanding the theories can help with diagnosis and patient care.

    Blood supply to the hand

    Play Episode Listen Later Jan 10, 2025 5:58


    The radial and ulnar arteries both supply blood to the hand and meet as two arches that send branches off to the fingers. This anatomy gives redundancy for the blood supply to the hand so let's talk about where these arteries run and how they branch.

    Thumb movements

    The names of the movements of the thumb can be tricky to remember, but knowing the movements gives you the names of the muscles that cause these movements.

    Relating the movements of the hand to the nerves responsible is an important clinical skill. Let's see if I can describe the movements of the wrist and fingers, and the nerves that trigger these movements in 5 minutes.

    Erection

    Did you know that alongside the pulmonary arteries taking poorly oxygenated blood to the lungs run bronchial arteries carrying well oxygenated blood? Where do they come from, and where does this blood go to?

    Ureters

    Play Episode Listen Later Nov 15, 2024 6:39


    The ureters carry urine from the kidneys to the bladder, and are muscular tubes lined by a urothelium. They use peristaltic contractions to send the urine in the right direction so do not rely on gravity, and because they run from the mid-abdomen down to the true pelvis they receive a number of arterial branches as they travel and likewise use nerves from a number of spinal levels to send the pain of a kidney stone obstruction back to the brain.

    Kidneys

    Play Episode Listen Later Nov 8, 2024 5:55


    The kidneys manage the amount of water and salts in the body, regulate blood pressure, stimulate red blood cell synthesis, and remove toxins among other jobs. Let's talk about the key points of their anatomy for 5 minutes.

    Breathing anatomy

    Play Episode Listen Later Oct 25, 2024 6:11


    The anatomy of breathing uses a number of muscles to change pressures inside the thorax and adds more muscles and more movements when we need more air. At rest you're just using your diaphragm and the elastic recoil of the lungs themselves, when you're a little more active and running around the intercostal muscles start to move the ribs, and when you really need to pull air in and push it out you can take advantage of accessory muscles of respiration that might not normally move the ribs.

    Cochlea and Hearing

    In this episode, we unravel the anatomy of the cochlea, the intricate organ that makes hearing possible. Discover how this tiny structure converts sound waves into electrical impulses, bridging the gap between the ear and the brain.

    Intercostal muscles

    Play Episode Listen Later Oct 11, 2024 6:45


    Three layers of intercostal muscles run between the ribs to form the thoracic wall, resist the pressure changes of respiration and move the ribs. What would happen if these muscles were not there?

    Lymph node anatomy

    Play Episode Listen Later Oct 4, 2024 6:30


    Lymph nodes are little bean shaped structures filled with the cells of the immune system and dotted around the body. Pathogens from skin injuries or that enter the body in other ways are passed to a lymph node and the cells here can respond. They are major parts of the immune system but metastatic cancer cells may also pass here, get stuck and continue to proliferate. This is important anatomy then, so let's quickly talk about it in around 5 minutes of podcast world time.

    Swallowing anatomy

    Swallowing is a sequence of events that must occur in a well ordered manner to ensure food and drink goes to the oesophagus and not into the airway. What is this sequence and what cranial nerves do we need to worry about?

    Popliteal fossa

    The mediastinum is a region within the thorax between the lungs. In here we find the heart, great vessels, trachea, oesophagus and other anatomical structures. We can further describe where these structures are by dividing the mediastinum up into superior and inferior parts, and the inferior mediastinum up into anterior, middle and posterior medastinal compartments.

    Play Episode Listen Later May 10, 2024 6:33


    The coeliac trunk is a branch of the aorta in the abdomen that supplies blood to the stomach, liver, gallbladder, pancreas, spleen and parts of the duodenum and oesophagus. It is important because its branches supply blood to important organs but also because stomach and duodenal ulcers can erode through these arteries and cause significant bleeding. The anatomy here is difficult to describe but let's try and describe the branches of the coeliac trunk and how they supply blood to the organs that they are reponsible for.

    The basal ganglia should be called the basal nuclei, and are also referred to as the corpus striatum. This demonstrates one of the problems with studying neuroanatomy as terms seem to overlap.

    One of the huge reasons that exercise and a good diet are so important is atherosclerosis. This pathology describes a change to the walls of arteries that can cause narrowing, rupture or blocking of an artery. If this occurs in an artery supplying blood to the heart or the brain this will probably cause death, and is a leading cause of death in western countries.
