Obturator Foramen

Obturator Foramen The obturator foramen is indicated in this diagram. The obturator foramen lies inferior to the acetabulum of the pelvis and is an opening between the ischium and pubic bones. It is covered almost entirely by the obturator membrane. A small gap is left between the superior margin of the obturator membrane and the pelvic bone above, known as the obturator canal, which allows a few vessels and nerves to pass out from the pelvic cavity to communicate with the lower limb. There are three structures which pass through the obturator canal: Obturator artery Obturator vein Obturator nerve Learn …

Pterion

Pterion The structure indicated is known as pterion. Pterion is the name given to the region on the lateral aspect of the skull where four bones are joined: Parietal bone Squamous part of temporal bone Front bone Greater wing of sphenoid bone Pterion is a point of clinical significance – the skull is very thin at this point. In addition to being structurally weak due to being the point of union between several bones, it also lies over the anterior division of the middle meningeal artery. Fracture of the skull at this point can therefore disrupt the middle meningeal artery, …

Cortical Homunculus

Cortical Homunculus The diagram illustrates the cortical homunculus. The cortical homunculus visually portrays the anatomical divisions of the primary motor cortex and the primary somatosensory cortex. The word “homunculus” comes from the Latin word which translates as “little man”. It represents how our body is perceived within the brain and how the neurons are distributed in these areas in order to create this perception. What immediately stands out is that the size of a body area is not proportional to its representation in the cortical homunculus – certain areas such as the hands, lips and face occupy disproportionately large areas …

Carpal Tunnel

Carpal Tunnel Represented in this diagram is the carpal tunnel. The carpal tunnel is formed by an arch of carpal bones and the flexor retinaculum, found on the anterior aspect of the wrist. The flexor retinaculum attaches on the radial side to the scaphoid tubercle and the trapezium bone; on the ulnar side it attaches to the hook of the hamate and the pisiform. Its attachment over the arch of carpal bones converts the space into a tunnel which allows for the passage of several tendons and the median nerve. The carpal tunnel contains nine long flexor tendons and the …
