Cranium- head mandible- jaw phalange’s- fingers patella- knee humorous- upper arm
What are the 4 different types of bones found in the body? Know examples for each type.
LONG BONES- Legs, arms,toes= compact bone tissue SHORT BONES- = irregular cubes, ankle, bone of the wrist FlAT BONES - skull, ribs, hips= protect organs IRREGULAR BONES- irregular shape, vertebrae SESAMOID- Small bones developed in tendons around joints- Patella
What are the 5 sections of the vertebrate? What is the responsibility of each section? How many vertebrae make up each section
CERVICAL- 7- support head THORACIC - 12- connect rib cage LUMBAR - 5- Large weight carrier SACRUM- 5 fused- fused to pelvis- Distribute the weight of the upper body COCCYX-4 fused- tail, site for muscular attachment
what are joints
JOINT is the part of the body where two or more bones meet to allow movement
To explain different joint movements, eg flexion/ extension etc
FLEXION: Angle between two bones is decreased EXTENSION: Angle between two bones is increased ABDUCTION: Movement of body part away from midline of body. ADDUCTION: Movement of body part toward midline of body. ROTATION: When a bone turns on its own axis within a joint. CIRCUMDUCTION: rotation of shoulder PRONATION: face palm down SUPINATION: face palm up PLANTARFLEXION: ankle pointing toes downward DORSIFLEXION: ankle pointing toes upwards INVERSION: turn sole of foot inwards EVERSION: turn sole of foot outwards Place- Location Action
