UNIT 1.1 - SKELETAL SYSTEM Flashcards
Superior
Towards the head of the body (eg- the humerous is superior to the ulner)
Inferior
Away from the head of the body; lower (eg - tibia is inferior to pelvic girdle)
Anterior
Front (eg - patella is located on the anterior side of the leg)
Posterior
Back (eg - scapula is on the posterior side)
Medial
Towards the midline of the body
Lateral
Away from the midline of the body
Proximal
Towards or nearest to the trunk or point of origin of a part (eg - proximal end of femur joins with pelvic bone)
Distal
away from or farthest from the trunk or point of origin of a part (eg - metacarpals located at distal end of ulna)
Axial Skeleton
the centre of the human body. It houses and protects vital organs. Consists of skull, ribs, sternum, vertebral column
Appendicular skeleton
Consists of pectoral girdle, humerus radius, ulna, carpals, etc
Function of axial skeleton
Has 2 main functions: first to protect and support organs in dorsal and ventral cavities. Secondly, it creates surface for attachment of muscles. Joints within the axial skeleton provide limited movement. Made up of 126 bones. Provides stability, balance and bodily structure.
Function of appendicular skeleton
Proviedes movement and joints are not fused. Allows a person to move their limbs during movement
Long bones
humerus, femur, fibula, tibia, radius, ulna, metacarpal, metatarsal, phalanges
Short bones
Tarsals, carpals
Irregular bones
vertebrae, sacrum
