muscle skelital integumentary system
| Term | Definition |
|---|---|
| the maintenance of a stable internal environment | homeostasis |
| group of similar cells working together | tissue |
| covers and protects underling tissue sticks together and forms a sheet ex. skin and lining the mouth | epithelial tissue |
| sends electrical signals through the body found in brain nerves and sense organs | nervous tissue |
| made of cells that can contract and relax to make movement | muscle tissue |
| joins, protects, supports, insulates, nourishes, cushions organs | connective tissue |
| two or more tissues working ex. heart bladder stomach | organ |
| organs working together ex. digestive system, reproductive system | organ system |
| responsible for protection of heart and lungs | ribs |
| responsible for protection of brain | cranium/skull |
| responsible for protection of the spinal cord | vertebrae |
| pull on bones to produce movement | skeletal muscles |
| made by cells called osteoblasts | bone |
| two different types of bone tissue | compact / spongy |
| does not have any visible open spaces provides more stretch and support contains blood and bone cells contains blood vessels | compact bone |
| has many open spaces make bone lighter found at ends of long bones acts like trusses of a bridge | spongy bone |
| soft tissue in the bone | marrow |
| produces red blood cells | red marrow |
| stores fat | yellow |
| most bone starts out like this | cartilage |
| soft flexible tissue witch is replaced by bone | cartilage |
| where two or more bone connect | joint |
| strong elastic bands of connective tissue that keeps two bonds together poor blood flow decreases in oxygen and nutrients there is poor repair to the ligaments | ligaments |
| an organ that can relax contact and provide force to move body parts | muscle |
| muscle found in digestive tract and blood vessels | smooth |
| found only in the heart | cardiac |
| attach to bones for movement and help protect your inner organs | skeletal |
| under your control ex. arms neck leg | voluntary |
| not under your control ex. heart stomach lungs | involuntary |
| strands of tough connective tissue that connects skeletal muscle to bones | tendon |
| a muscle that bends part of your body ex. biceps | flexor |
| a muscle that straitens part of your body ex. triceps | extendor |
