Study Notes

Anatomical Position and Terms

Anatomy is a descriptive science studying body parts and their relationships.
Anatomical position: a standard position for describing body parts.
- Person stands upright, feet flat on the floor, face forward, arms at sides, palms facing forward
Different body positions:
- Supine: lying face up
- Prone: lying face down
Body regions: head (cranial and facial), neck, thorax (chest), abdomen, pelvis, upper limb, lower limb.
Body cavities
- Major cavities:
  - Abdominal: largest, upper and lower parts separated by diaphragm
  - Thoracic: separated from abdominal by diaphragm
  - Cranial: in skull, containing brain
  - Vertebral canal: within vertebrae, contains spinal cord
- Other cavities: oral, nasal, orbital, middle ear

Planes of the Body

Sagittal: divides body into left and right
- Midsagittal: equal halves
- Parasagittal: not equal halves
Coronal (Frontal): divides body into front and back
Transverse (Horizontal): divides body into upper and lower sections

Anatomical Terminology

Medial: towards the midline of the body
Lateral: away from the midline of the body
Superior (Cranial): above/towards the head
Inferior (Caudal): below/towards the feet
Proximal: closer to the origin of a body part
Distal: farther from the origin of a body part
Anterior (Ventral): front of the body
Posterior (Dorsal): back of the body
Superficial: near the surface
Deep: away from the surface

Anatomical Movements

Flexion: decrease in angle between two body parts
Extension: increase in angle between two body parts
Abduction: moving a limb away from the midline
Adduction: moving a limb toward the midline
Medial rotation: turning a bone inward
Lateral rotation: turning a bone outward
Circumduction: circular movement of a limb
Elevation: raising a body part
Depression: lowering a body part
Protraction: moving a body part forward
Retraction: moving a body part backward
Inversion: turning the sole of the foot inward
Eversion: turning the sole of the foot outward
Supination: rotating forearm so palm faces upward
Pronation: rotating forearm so palm faces downward
Opposition: touching the thumb to the other fingers on the same hand.

Skeletal System

Axial skeleton: skull, vertebral column, ribs, sternum
Appendicular skeleton: limbs
Bone types (classified by structure/shape)
Bone function: framework, support for body, muscle attachment, blood cell production

Other Systems

Learning objectives include the different body systems, with emphasis on their anatomy
