What is the Yellow Marrow? fatty connective tissue
What is the Skeletal System? supports and protects the body (bone)
What is the Nutrient Artery? supplies oxygen and nutrients to the shaft of the bone
What is the Integumetary System? protects the body from pathogen invasion, water loss, and physical trauma(skin)
What is the Muscular System? supports and enables the body to move muscles
What is the Nervous System? detects information from the enviorment and controls body functions(brain, soinal chord, nerves, sense organs, receptors)
What are the Cardiovascular System? transports nutrients and waste to and from all body tissue(heart, blood, blood vessels.
What are the Sensory Neurons? bring messages to CNS
What are the Motor Neurons? carry messages from CNS
What are the Interneurons? between sensory & motor neurons in the CNS
What is the Dendrite? receive stimulus and carries it impulses toward the cell body
What is the Cell Body With Nucleus? nucleus & most of cytoplasm
What is the Axon? fiber which carries impulses away from cell body
What is the Schwann Cells? cells which produce myelin or fat layer
What is the Myelin sheath? lipid layer around the axon
What is the Node of Ranvier? gaps or nodes in the myelin sheath
How do Impulses travel? impulses travel from dendrite to cell body to axon
What is the Excretory System? the system that removes watse from your body and controls water balance ( kidneys, urters, bladder, uthera )
What is the Respitory System? takes in oxygen and eliminates carbon dioxide (air passages, lungs)
What is the Digestive System breaks down food and absorbs nutrients (mouth, esophagus, stomach, liver, pancreas, small, and large intestines)
What is the Immune System the cells, tissues, and organs that protect the body from disease (lymph nodes and vessels, white blood cells)
What is the Endocrine System mantains homeostasis, regulate metabolism, growth, behavior, development, and reproductive (endocrine glands, hormones)
What is the Reproductive System system of organs involved in producing offspring ( ovaries, uterus, mammary glands, testes)
What is the Muscle Tissue? compsed of cells that can contract (skeletal, smooth, and cardiac)
What is the nervous Tissue? contains neurons that receive and transmit messages as electrical charges
