Functions of the skeletal system
Provide framework for the human body, structure, protect internal organs
Ossification
the process cartilage is changed into bone
Long bones
Cylinder-like in shape and longer than it is wide, these are the strongest bones in your body
Examples of the long bone
Humerus (upper arm); femur (thigh); clavicle (collarbone); radius (forearm); ulna (forearm); phalanges (fingers and
toes); tibia (lower leg); fibula (lower leg
Short bones
equal in width and length
,Examples of short bones
carpal (wrist) and tarsal (ankle) bones
Flat bones
Flat and plate-like
Examples of flat bones
bones of the skull (cranial bones); rib cage; scapula (shoulder blade
Irregular bones
irregular in shape
Examples of irregular bones
vertebrae (spine); hip bones; mandible ( jaw)
,Sesamoid bones
small and round; embedded in a tendon
Examples of sesamoid bones
patella (kneecap)
Immovable joints (fibrous)
allow little or no movement at the joint (ex: skull, rib cage)
Partly movable joints (cartilaginous)
permit slight movement (ex: joints between adjacent vertebrae in the spine)
Movable joints (synovial joints)
allow bones to move freely (ex: hip, knee joints)
, skeletal muscle tissue
is voluntary; made up of three layers of tissue
skeletal muscle tissue function
allows for movement by pulling on our bones; Voluntary movement, produces heat, protects organs
cardiac muscle tissue
is involuntary; found only in the heart
cardiac muscle function
allows blood to pump through the circulatory system
