How Nerves Work Openness In the nervous system there are sections called: a. Receptor: a tool to receive excitatory usually a sensory tool b. Effector: a tool to respond to stimuli in the form of muscles and glands c. Sensory nerve cells: nerve fibers that carry stimuli to the brain d. Motor nerve cells: nerve fibers that carry stimuli from the brain e. Connector nerve cells: the motor nerve cells or nerve cells one with another nerve cell.
Scheme of conscious motion Excitatory receptors - sensory nerve cells - the brain-motor nerve-effector cell-response
Hormone System The hormone is one of the coordinate system in the body by using a fluid circulated by the blood vessels. By using slower stimulation hormone responses given. One advantage of coordination using a hormone that is with little hormone can affect the organs that become targets. Pituitary (pituitary). These glands are glands that produce most types of hormones. Its location in the brain Kinds of hormone produced: 1) Somatotropin: functions to accelerate growth 2) Prolactin: functions accompany mammary gland activity 3) Tireotropin: influence of thyroid gland activity 4) Adnecorticotropin: adrenal glands affect the activity of the cortex 5) Gonadotropin: influence of ovarian or testicular activity 6) Vasopressin: regulate blood vessel constriction 7) Oxytocin: regulate muscle contractions of the uterus in childbirth. The thyroid gland (thyroid gland) The hormones produced by the thyroxine and function regulate growth and metabolism. Location of the glands around the Adam's apple.
Thyroid glands of children (parathyroid gland) Located near the thyroid. Parathormone hormone that is produced with the function of maintaining levels of calcium and phosphorus in the blood. Adrenal glands (adrenal gland) Located attaches to the top of the kidneys. The skin to produce cortisone which controls metabolism and regulates water and salt balance.
Being part marrow (medulla) produces adrenaline (epinephrine) that affect the function of heart rate, regulate bladder muscles also regulate blood sugar levels by changing glycogen into glucose.
Pancreas gland Pancreatic islands of Langerhans produce insulin. The function of these hormones regulate blood sugar levels by altering glucose into glycogen.
Gonad 1. In men Located at the testes. The hormone produced by the most important being the testosterone that serves to maintain the process of sperm formation and growth characteristic abnormalities of secondary 2. In women Located in the ovary. Hormones produced: 1) Estrogen, to maintain the formation of ova and characteristic abnormalities of secondary 2) progesterone, regulate the formation of the placenta and milk production.
