Study Notes
Standard Anatomical Position
- The subject stands erect facing the observer.
- The head is level with eyes facing forward.
- Feet are level on the ground and directed forward.
- Upper limbs are at the sides, palms facing forward.
Terminology - Part of the Body
- Head (cephalic): Parts include skull (cranial), face (facial), chin (mental), neck (cervical), chest (pectoral), armpit (axillary), arm (brachial), and other body parts.
- Trunk (thoracic): Includes chest, abdomen, and other relevant body parts.
- Upper limb: Includes arm (brachial), front of elbow (antecubital or cubital), forearm (antebrachial), wrist (carpal), palm (palmar), hand (manual), and other body parts relevant to the arm and hand.
- Lower limb: Includes thigh (femoral), knee (patellar), leg (crural), ankle (tarsal), foot (dorsal), toes (digital and phalangeal), and other relevant body parts.
- Back of the body: Includes parts such as back of torso, base of skull, shoulder blades (scapular), spinal column (vertebral), back of elbow (olecranal), between hips (sacral), buttocks (gluteal), and other parts of the back.
Terminology - Directions
- Anterior (ventral): Front or in front of
- Posterior (dorsal): Back or in back of
- Cranial: Head end of the body
- Caudal: Tail end of the body
- Superior: Upper or above another
- Inferior: Lower or below another
- Medial: Toward the midline or median plane of the body
- Lateral: Away from the midline or median plane of the body
- Proximal: Toward the point of attachment to the body or the body trunk
- Distal: Away from the point of attachment or origin, farthest from the trunk
- Superficial (external): On or near the surface of the body
- Deep (internal): Inside the body, away from the surface
Terminology - Planes of Movements
- Sagittal: Right - Left
- Frontal: Front - back
- Transverse: Superior - Inferior
Osteology (Study of Bone)
- Function: Supporting and protecting (e.g., brain, spinal cord, heart); movement; storing minerals (e.g., phosphate, calcium); hematopoiesis (blood cell formation in red bone marrow).
-
Bone Tissue:
- Osteocyte: Bone cell
- Osteoblast: Cell forming osteocyte
- Osteoclast: Cell breaking down osteocyte
Osteology (Human Skeleton)
- Human skeleton contains approximately 206 bones.
- Axial skeleton comprises 80 bones.
- Appendicular skeleton comprises 126 bones
Osteology (Bone Shapes)
- Long bones: Examples include femur and humerus
- Short bones: Examples include carpals and tarsals
- Flat bones: Examples include sternum, ribs, and scapula
- Irregular bones: Examples include vertebrae and hip bones
- Sesamoid bones: Examples include patella
Osteology (Bony Landmarks)
- Includes elevations/projections (e.g., processes, rami, ridges, tubercles, trochanters, and tuberosities); depressions (e.g., fossae, grooves, or sulci); openings (e.g., foramina, and meatus) ; other landmarks.
Arthrology (Study of Joints)
- Joint Naming: Joints are named based on the bones forming them. Examples include humeroulnar, glenohumeral, acromioclavicular, and hip (coxal) joints.
-
Joint Structures:
- Fibrous joint: Minimal joint cavity, dense connective tissue, primarily immovable.
- Cartilaginous joint: Cartilage between bones, increases flexibility.
- Synovial joint: Most mobile, contains a joint cavity, synovial fluid, and articular cartilage.
Arthrology (Joint Movement)
-
Degree of Mobility:
- Synarthrotic: Little or no movement
- Amphiarthrotic: Slightly movable
- Diarthrotic: Highly movable
- Physiological Movements: Flexion, extension, abduction, adduction, external rotation, internal rotation, pronation, supination, roll, glide, and spin.
- Accessory Movements: Give or play, essential for full range of motion.
Myology (Range of Motion - ROM)
- Three types of motion: Active, Resisted, Passive
