| function of skeletal system | 1.provide support and protection 2.store calcium and other minerals 3.forms blood cells |
| major organs in muscular system | 1.skeletal muscles and associated tendons and 2.aponeuroses ( tendinous sheets ) |
| function of muscular system | 1.movement 2.protection and support 3.generates heat. |
| major organs in nervous system | 1.brain 2.spinal cord 3.peripheral nerves 4.sense organs |
| function of nervous system | 1.response to stimuli 2.coordinate and moderate other organ systems 3.provide sensory information about external conditions. |
| major organs in endocrine system | 1.pituitary gland 2.thyroid gland 3.pancreas 4.adrenal gland 5.gonads (testes and ovaries) 6.endocrine tissue. |
| function of endocrine system | 1.direct long term changes in other organ systems 2.adjust metabolic activities and energy use. 3.controls functional and structural changes during growth. |

| what is homeostasis? | stable internal environment |
| steps of homeostasis? | 1.stimulus: change 2.receptor: detects change 3.input: sends info to control center 4.output: info sent to effector 5.response: effector reduces the change and homeostasis is restored |
| Regulation of homeostasis? | 1.auto-regulation: regulates itself. 2.Extrinsic regulation: nervous or endocrine system regulate homeostasis of other organ systems 3.positive and negative feedback |
| positive feedback | strengthens the change |
| negative feedback | change is controlled |
| function of ventral body cavity | 1.provide protection 2.allow movement of organs 3.lining prevent friction |
| what does ventral body cavity divide into? | 1.thoracic cavity 2.abdominopelvic cavity |
| what does thoracic divide into? | 1. right pleural cavity: surrounds right lung 2. mediastinum: has trachea esophagus and major vessels. and percardial cavity: surrounds heart. 3. left pleural cavity: surrounds left lung |
| what does abdominopelvic cavity divide into? | peritoneal cavity:, that divides into abdominal cavity: degestive glands and orangs, and pelvic cavity: urinary bladder, reproductive organs, and last portion of digestive tract. |
| what are retroperitoneal organs? | organs that lie between peritoneal lining and muscular wall of abdominal cavity. |
