Study Notes
Kinesiology Overview
- Kinesiology refers to the study of human movement.
- Anatomy focuses on the structure of the human body.
- Physiology examines the functioning of the human body.
Anatomical Position
- Recognized as the reference position for locating body structures:
- Person stands facing forward.
- Feet face forward and are slightly apart.
- Palms are facing forward.
- Arms are straight and positioned slightly away from the body.
Anatomical Planes
- Planes are used to divide the body into sections; movements occur within these planes:
- Sagittal Plane: Divides the body into left and right sections.
- Frontal Plane: Divides the body into anterior (front) and posterior (back) sections.
- Transverse Plane: Divides the body into superior (upper) and inferior (lower) sections.
Anatomical Axes
- Axes are points around which the body rotates and are perpendicular to anatomical planes:
- Longitudinal Axis: Runs vertically through the head and aligns with the transverse plane.
- Horizontal Axis: Passes through the hips and aligns with the sagittal plane.
- Antero-posterior Axis: Extends from the belly button to the back, aligning with the frontal plane.
The Skeletal System
- Comprises 206 bones, cartilage, and teeth, displaying variability among different bones.
Roles of the Skeleton
-
Primary Functions:
- Protection of vital organs.
- Facilitates body movement.
- Provides structural support.
- Stores minerals, predominantly calcium.
- Protects red blood cells produced in the marrow.
-
Additional Functions:
- Contributes to force generation.
-
Less Significant Functions Include:
- Support for knees.
- Weight distribution.
- Symmetry of the four limbs.
Parts of the Skeleton
-
Axial Skeleton (80 bones):
- Composed of the skull, rib cage, and spinal column.
-
Appendicular Skeleton (126 bones):
- Encompasses upper limbs and their attachments as well as lower limbs and the pelvic girdle.
Age and Gender Differences
- Women possess pelvis cartilage that accommodates childbirth.
- Men generally have a denser but more brittle skeleton compared to women.
