Anatomy of the Skull
The skull is the bony structure that forms the head. It consists of 22 bones that fuse together during childhood and adolescence. The skull protects the brain and sensory organs, such as the eyes, ears, and nose.
Anatomy of the Brain
The brain is the control center of the body. It consists of three main parts: the cerebrum, cerebellum, and brainstem. The cerebrum is the largest part of the brain and is responsible for thinking, learning, and memory. The cerebellum coordinates muscle movements, and the brainstem regulates basic functions such as breathing and heart rate.
Anatomy of the Intestine
The intestine is a long, thin tube that absorbs nutrients from food. It consists of two main parts: the small intestine and large intestine. The small intestine is responsible for most nutrient absorption, while the large intestine absorbs water and electrolytes.
Anatomy of the Eyes
The eyes are the organs of sight. They consist of the cornea, iris, lens, retina, and optic nerve. The cornea is the clear layer on the front of the eye, while the iris is the colored part. The lens focuses light on the retina, which sends visual signals to the brain via the optic nerve.
