How do musculoskeletal and cardiorespiratory systems influence and respond to movement?
Skeletal system
Terminology:
Anterior: Toward or on the front of the body: in front of
The pectorals are on the anterior aspect of the body
Posterior: Towards or on the back of the body: behind
The rhomboids are on the posterior aspect of the body
Superior: Toward the head or upper part of a structure: above
The humerus is superior to the radius
Inferior: Toward the lower part of a structure: below
The tibia is inferior to the femur
Medial: Toward or at the midline of the body: inner side
The adductors are on medial to the abductors
Lateral: Away from the midline of the body: outer side
The abductors are on the lateral aspect of the leg
Proximal: Closer to the origin of a point of reference
The elbow is proximal to the wrist
Distal: Further from the origin or point of reference
The foot is distal to the knee
Three planes of the body * Sagittal – vertical plane which cuts the body into left and right * Frontal or lateral plane - lies vertically however divides the body into anterior and posterior parts. * Transverse plane lies horizontally and divides the body into superior and inferior parts.
Three planes of the body * The sagittal axis passes horizontally from posterior to anterior and is formed by the intersection of the sagittal and transverse planes. * The frontal axis passes horizontally from left to right and is formed by the intersection of the frontal and transverse planes. * The vertical axis passes vertically from inferior to superior and is formed by the intersection of the sagittal and frontal planes.
Skeletal system consists of 206 bones, joints between bones, cartilage and ligaments
Provides: framework, maintains posture, protects internal organs, produces red blood cells in bone marrow, provides and maintains calcium reserves for bone growth and repair, serves as levers for body
