List and define the three parts of the nervous system
Central- brain,spinal cord, involuntary 5 senses
Peripheral- system of nerves that connects the peripheral parts to the CNS
Autonomic-involuntary. breathing and heart beating. 
what are nerves?
whitish cords made up of bundles of nerve fibers held together by connective tissue 
The two types of nerves 
sensory carries impulses from sense organs to brain, motor carries impulses from brain to muscle or glands 
what are receptors 
Sensory nerve endings
List and defined the nerves of the arm 
Digital- supplies the fingers
Radial- supplies, the thumb side of the arm and back of hand
Ulnar- affects the little finger side of the arm and palm of the hand 
Median- supplies, the arm and hand
how many pairs of cranial nerves arise from the base of the brain and the brain system? 
12
The study of the structure and composition of tissue 
histology
The dense, active Proto plasm found in the center of a cell 
nucleus 
takes in nutrients, breaks them down and creates energy for the cells. It works to keep the cell full of energy. 
mitochondria
The part of the cell that encloses the Protoplasm and permitted soluble substances to enter and leave 
cell membrane
muscles are connected to bones by
tendons 
bones are connected to each other by 
 ligaments
The two types of joints 
movable and immovable 
The human head contains 22 bones divided into two groups. What are these groups called? 
cranium and facial bones 
what are capillaries 
tiny, thin walled blood vessels connect to smaller arteries to venules 
three facts about blood 
8 to 10 pints in the human body, salty and sticky, normally 98.6°F. 
what are the five functions of the blood? 
carries water, oxygen nutrients and minerals. carries a Way carbon dioxide. helps to equalize the bodies temperature. Aids in protecting the body from harmful bacteria infections. Closes injured blood vessels by blood clot. 
what is the difference between white and red blood cells? 
White blood cells destroy disease, causing microorganisms, red blood cells carry oxygen to the body cells 
what is the difference between platelets and plasma
platelets contribute blood clotting process. Plasma is the fluid part of blood that acts as a delivery system.
List the endocrine glands and their functions 
- pineal is sexual development, sleep and metabolism.
- pituitary effects almost every physiological process of the body.
3.Thyoid secretes, hormones that regulate the bodies, metabolism, heart & digestive function, brain, development, and maintenance of bone mass. - parathyroid regulates blood calcium and phosphorus levels 
what is the digestive system? 
it breaks down food 
what is the reproductive system? 
produces children 
what is the lymphatic system? 
protects the body from disease by developing resistances 
what is the integumentary system? 
largest organ of the body. first line of defense against infection and water loss 
What is the muscular
Covers shapes and supports the skeletal tissue
what is the skeletal system
Forms of physical foundation of the body
what is the circulatory system?
Delivery of the blood through the body 
what is the endocrine system?
Affects growth, development, sexual activities, and normal regulatory processes of the body 
What is the excretory system?
Elimination of waste matter
what is the nervous system?
Carries messages through the central nervous system
