Nervous & Endocrine System

• the central nervous system is made up of the brain and the spinal cord
• the peripheral nervous system transfers messages to and from the central nervous system, around the edges of the core, and is made up of the SNS and ANS
• the autonomic nervous system regulates functions that are not consciously controlled eg breathing and heart rate
• the parasympathetic nervous system puts the body in its usual resting state eg decreases the heart rate and stimulates digestion
• the somatic nervous system controls muscle movement and receives information from sensory receptors, contains sensory and motor neurons
• the parathyroid gland is located in the neck near the thyroid
• the parathyroid gland produces the parathyroid hormone
• the parathyroid gland increases the levels of calcium in the body
• the pituitary gland is located in the base of the brain
• the pituitary gland produces LH and FSH
• FSH is the hormone involved in releasing the egg, and LH is the hormone involved in maturing the egg
• the thyroid gland is located in the neck
• the thyroid gland produces thyroxine
• thyroxine produces energy and helps with metabolism
• the pineal gland is located in the brain
• the pineal gland produces melatonin
• melatonin is the hormone involved in helping control the sleep/wake cycle
• the pancreas is located under the liver
• the pancreas produces insulin and glucagon, which helps with digestion and glucose provides energy
• the thymus gland is located in the chest and helps with immunity
• the endocrine system: helps to regulate the activity of cells and organs in the body
