Study Notes
Skeletal System Divisions
- The appendicular skeleton includes the bones of the upper and lower limbs, and the bones that attach them to the axial skeleton
Anatomical Terminology
- Abduction: Movement of a body part away from the median plane
- Adduction: Movement of a body part towards the median plane
- Dorsiflexion: Bending the ankle towards the shin
Bone Types
- Flat bones: Thin and flat, often curved
- Short bones: Nearly equal in length and width, almost cube-shaped
- Hyaline cartilage: Found in joints, providing smooth surfaces for articulation
Bone Surface Markings
- Facet: Smooth, flat articular surface
- Fossa: A shallow depression that houses a tendon
Anatomical Directions
- Medial: Closer to the midline of the body
- Lateral: Further from the midline of the body
- Anterior: Closer to the front of the body
- Posterior: Closer to the back of the body
- Superior: Closer to the head
- Inferior: Further from the head, towards the feet
- Proximal: Closer to the origin or trunk
- Distal: Further from the origin or trunk
Anatomical Position
- Anatomical position: Standing erect, facing forward, arms at sides, palms facing forward
- Prone: Lying face down
- Supine: Lying face up
Body Planes
- Sagittal plane: Divides the body into right and left sides
- Frontal plane: Divides the body into anterior and posterior sections
- Transverse plane: Divides the body into superior and inferior sections
Anatomy
- Anatomy: The study of the structure and relationships of body parts
Skeletal System Function
- Skeletal System Functions: Support, movement, protection, mineral storage, hematopoiesis (blood cell formation)
Major Body Regions
- Head: Contains the brain, sensory organs
- Neck: Connects the head to the trunk
- Trunk: Includes the thorax (chest), abdomen, and pelvis
- Upper limbs: Include the arms, forearms, hands
- Lower limbs: Include the thighs, legs, feet
Embryology
- Embryology: The study of the structure and development of an embryo
Joints
- Fibrous joints: Held together by fibrous connective tissue (e.g., sutures in the skull)
- Cartilaginous joints: Held together by cartilage (e.g., synchondroses, symphyses)
- Synovial joints: Freely movable joints with a joint cavity (e.g., knee, shoulder)
- Synarthrosis: Immovable joint
- Amphiarthrosis: Slightly movable joint
- Diarthrosis: Freely movable joint
- Hinge joints: Allow flexion and extension (e.g., elbow, knee)
- Ball and socket joints: Allow triaxial movement (e.g., shoulder, hip)
- Pivot joints: Allow rotation around a central axis (e.g., between radius and ulna)
- Gliding joints: Allow sliding or gliding movements (e.g., between carpal bones)
- Saddle joints: Allow movement in two planes (e.g., between thumb and trapezium)
Muscle Contraction
- Isometric contraction: Muscle contraction without changing length
- Isotonic contraction: Muscle contraction with a change in length
Muscle Roles
- Antagonist muscle: Opposes the action of the prime mover
Fascia
- Tendons and aponeuroses: Connect muscle to bone
- Deep fascia: Strong fibrous tissue that surrounds muscles and muscle groups
Nerves
- Sensory nerves: Carry impulses from receptors to the central nervous system
- Motor nerves: Carry impulses from the central nervous system to muscles and glands
- Spinal nerves: Innervate the body below the head
- Cranial nerves: Innervate the head and neck
Other Structures
- Tendon sheaths: Tube-like structures that surround tendons, allowing for free movement
