A cyst is a sac-like structure that is often filled with fluid, or some other substance. There are many types of cysts such as epidermoid cysts, pilar cysts and Baker’s cysts. One type of cyst that is commonly found in the wrist or hand is the ganglion cyst.   Ganglion cysts form near joints or tendons. […]READ POST

This February we celebrate Hearth Month! Heart Month encourages everyone to focus on their cardiovascular health by raising awareness of heart disease and other heart-related conditions. A great way to understand what heart disease is, is to first understand the anatomy of the heart.  The heart is composed of four main chambers. There are two […]READ POST

In the male reproductive system, the testes are suspended by the spermatic cord. Within each spermatic cord are several structures. These include the testicular artery, testicular veins, lymphatics, the deferent duct and testicular nerves.  The testicular arteries arise from the abdominal aorta and descend into the testes. They supply the ureters, testes, and epididymis.   The […]READ POST

Spermatogenesis is the process whereby spermatozoa are formed. Spermatogenesis has two stages: spermatocytogenesis and spermiogenesis.  Spermatocytogenesis is the first stage of spermatogenesis, whereby spermatogonia develop into spermatocytes and eventually spermatids. Spermatogonia are the germ cells of spermatozoa. Type A dark (Ad) spermatogonia undergo mitotic division at irregular intervals giving rise to either a pair of […]READ POST

Smooth muscle is one of the three types of muscle found in the body; cardiac and skeletal muscle being the other two. Smooth muscle is an involuntary muscle, meaning it is not under conscious control. It is found almost everywhere in the body. For example, it can be found in the gastrointestinal tract, respiratory tract […]READ POST

The small intestine is a key part of the digestive system. Spanning 6-7m within the abdominal cavity, the small intestine has roles in digestion and absorption.   The small intestine is divided into three parts: the duodenum, the jejunum and the ileum. The first part, the duodenum, is the shortest section. It is about 25-30cm long. […]READ POST

The urinary system is important in maintaining homeostasis of the body. For example, the urinary system regulates levels of fluids and electrolytes within the body.  The urinary system consists of the kidneys, ureters, bladder and urethra. The kidney is composed of three layers: the capsule, the renal cortex and the renal medulla. The renal medulla […]READ POST

Specifically, from mosquitoes that are infected with a parasite from the genus plasmodium.   (1) When an infected mosquito bites your skin, it can transfer the parasite to you. (2) These parasites travel to the liver where they mature. The […]READ POST

Skeletal muscle is one of the three main types of muscle found in the body; cardiac and smooth muscle being the other two. Skeletal muscles are under voluntary control and are responsible for moving our bodies. Let’s explore the anatomy of skeletal muscle starting with one of the smallest units, the myofibril. Myofibrils are contractile […]READ POST
