IB Sports, Exercise, and Health Science Exam Questions with Correct Answers|
Latest Update Graded A+
long bones i.e. femur, metatarsals, and clavicle
most important bones for movement
short bones small and cube shaped and articulate with multiple bones
i.e. carpals of the hand and tarsals of the feet
flat bones usually have curbed surfaces and vary from being very thin to very thick
i.e. sternum, ribs, and pelvis
irregular bones have specialized shapes and functions
i.e. vertebrae, sacrum, coccyx
ligaments connect one bone with another bone
tendons connect a muscle to a bone
cartilage flexible connective tissue, sometimes serves as padding between two articulating
bones
joint where two or more bones come into contact or articulate with each other
-main function is to increase the mobility of the body and limbs
fibrous joint -have a thin layer of fibrous tissue connecting the edges of the two bones
, -no movement allowed at these joints
cartilaginous joint -bones separated by a fibrocartilage disc or a layer of hyaline cartilage
-limited movement allowed at these joints
synovial joint -most common
-most important for mobility
ball and socket joint i.e. shoulder
gliding joint i.e. between carpal bones
hinge joint i.e. elbow joint
pivot joint i.e. radioulnar joint
condyloid joint i.e. between the radius and carpal bones
saddle joint i.e. between the carpal bone and the metacarpal of the thumb
skeletal muscle -voluntary control
-striated appearance
-function: to move the skelton
-i.e. biceps
