 Median: divides the body into right and left sides  Sagittal: divides the body into right and left parts – parallel to the median plan (the “doing plane”)  Coronal (frontal): divides the body into front and back  Transverse: divides the body in half at the waist

 Anterior: Front or In Front  Posterior: Back or Behind  Medial: Towards the mid-line of the body  Lateral: Away from the mid-line of the body  Proximal: closer to the median plane or root of the limb  Distal: furthest from center  Superior: higher than the body – closer to the head  Inferior: Closer to the feet  Superficial: external

 Vertical Axis: through the head down to the feet (horizontal plane)  Horizontal Axis: goes through the hips (sagittal plane)  Sagittal Axis: goes through the belly into the back (vertical plane)

 Definition: Living substance mostly made of calcium phosphate and mineral salts

 Functions: To provide a structure for the body to provide attachments for muscles, to serve as a reservoir for minerals salts, protect vital organs, and to manufacture red blood cells

 The body is composed of 206 bones  The skeleton supports the entire weight of the body  26 bones in each foot  27 bones in each hand  24 ribs  33 vertebrae in the spine

 A.K.A the head  Provides a thick, protective layer over the soft brain tissue that controls the eyes, nose, mouth, and ears  Protects the place where delicate functions of thinking and learning take place (i.e. the brain)

 Barrel shaped  Protects vital organs such as the heart and lungs  Made up of 12 pairs of ribs  Top 7 attach to the breast bone or sternum  Next 3 are attached to cartilage  Remaining 2 pairs are unattached or called “floating ribs”

 Has 2 wide parts called girdles (hip and shoulder)  Each shoulder girdle has a clavicle and scapula  The pelvis (hip) girdle is shaped like a bowl
