InnerBody:  Endocrine System
United States

The hypothalamus is a part of the brain located superior and anterior to the brain stem and inferior to the thalamus. It serves many different functions in the nervous system, and is also responsible for the direct control of the endocrine system through the pituitary gland. The hypothalamus contains special cells called neurosecretory cells neurons that secrete hormones: Thyrotropin-releasing hormone (TRH) Growth hormone-releasing hormone (G

InnerBody: Nervous System
United States

The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts. The brain and spinal cord form the control center known as the central nervous system (CNS), where information is evaluated and decisions made. The sensory nerves and sense organs of the peripheral nerv

InnerBody:  Digestive System
United States

The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract).

Innerbody: Muscular System
United States

The muscular system is a system of tissues - called muscles - throughout the body which allow you to move. Most of the muscles in the body are under conscious control and are moved by commands sent to the muscles from the brain via the nervous system. However, some muscles (such as the cardiac muscles) are involuntary - that is, they move regularly without any conscious control. Except for the involuntary muscles, muscle fibers are connected to t

InnerBody:  Integumentary System
United States

The integumentary system is made up of the skin and its appendages (such as the fingernails, toenails and the hair). Its primary function is to protect the body from damage; it is also involved in temperature regulation and in the sense of touch. Upon exposure to sunlight, the integumentary system is also the primary vehicle for synthesis of vitamin D.

The kidneys are a pair of bean-shaped organs found along the posterior wall of the abdominal cavity. The left kidney is located slightly higher than the right kidney because the right side of the liver is much larger than the left side. The kidneys, unlike the other organs of the abdominal cavity, are located posterior to the peritoneum and touch the muscles of the back. The kidneys are surrounded by a layer of adipose that holds them in place an
