The Anatomy of Skin

The largest organ of your body is your skin (known as integument in the world of clinical anatomy). It includes the outer covering that protects your inside parts from the elements and from viruses and [more…]

A Clinical Look at Bone Composition and Structure

Your bones contain a matrix, osteoblasts, osteoclasts, osteocytes, and collagen fibers. Bones are hard structures because of the calcium that builds up in the matrix, but they retain a slight amount of [more…]

Clinical Anatomy Terms Describing Joints and Cartilage

A joint is the spot where two or more bones come together. Most joints allow for mobility, although several are fixed in their position. Joints are stabilized by ligaments and cartilage. Joints are classified [more…]

A Clinical Overview of Muscle Types

More than 600 muscles provide movement throughout the body. Cinical anatomy places muscles in three categories: skeletal muscle, cardiac muscle, and smooth muscle. Some muscle movements require a bit of [more…]

A Clinical Overview of the Nervous System

The nervous system is the control center for your body. It interprets the things your body senses, and it sends information to the muscles and glands, telling them what to do. It also runs the systems [more…]

What Organs Are Part of the Lymphatic System?

The lymphatic system includes a system of lymphatic capillaries, vessels, nodes, and ducts that collects and transports lymph, which is a clear to slightly yellowish fluid, similar to the plasma in blood [more…]

Clinical Overview of the Immune System

The immune system works hard to defend you from pathogens, including bacteria and viruses. It’s made up of leukocytes (white blood cells), proteins, and other tissues, including the lymphatic system. When [more…]

The lungs are pink spongy organs to the left and right of the heart that provide the means to get oxygen from the air into your red blood cells. Each lung has an apex at the superior end that rises above [more…]

What Is in the Thoracic Cavities?

The thoracic cavity is basically the chest, including everything between the neck and the diaphragm. It’s home to the thoracic organs and is protected by the thoracic cage. The heart and lungs are essential [more…]

The Anatomy of the Human Heart

The heart is a muscular four-chambered pump that beats constantly to keep blood flowing to the rest of your body. To make it’s workings easier to understand, clinical anatomy breaks the heart into three [more…]

What Is the Inguinal Region?

Clinical anatomy defines the inguinal region of the abdominal wall as the area between the anterior superior iliac spine and the pubic tubercle (in other words, the groin or lower lateral parts of the [more…]

The Anatomy of the Abdominal Wall

The abdominal wall is mainly made up of muscles and the tissues that support them. They combine with the spinal column to give the midsection its structure. The abdominal muscles cover the front and sides [more…]

How do the Stomach and Esophagus Process Food?

The food you eat makes its way to your stomach via the esophagus. It officially enters the abdomen when it passes through the esophageal hiatus of the diaphragm. The esophagus ends at the esophagogastric [more…]

The Physiology of the Small and Large Intestines

The digestive system processes the food you eat. Food travels via the esophagus into the stomach and then into the small and large intestines. The small intestine starts at the pylorus of the stomach and [more…]

Renal Anatomy

Renal anatomy refers to anatomy of the kidneys. The two kidneys filter the blood and form urine, which is transported to the urinary bladder by the ureters. Each kidney is capped by a suprarenal gland, [more…]

The Anatomy of the Perineum

The perineum is the region between the thighs inferior to the pelvic diaphragm. The boundaries of this region are the same as that for the pelvic outlet, namely the pubic symphysis, ischiopubic rami, sacrotuberous [more…]

Anatomy of the Brain: The Meninges

The meninges are the coverings of the brain. They protect the brain by housing a fluid-filled space, and they function as a framework for blood vessels. The meninges have three layers: the dura mater, [more…]
