Study Notes
Functions of the Skeleton
- Provides support, shape, and protection to the body.
- Facilitates movement and is integral to blood cell production.
Axial Skeleton
- Consists of the skull, vertebral column (spine), ribs, and sternum.
Appendicular Skeleton
- Comprises the pectoral girdle (shoulder area) and pelvic girdle (hip area).
Spine Structure
- Comprised of five parts: cervical (neck), thoracic (mid-back), lumbar (lower back), sacrum (base of spine), and coccyx (tailbone).
Metacarpals
- Located in the hand, contributing to the structure and movement of the fingers.
Bones of the Hand
- Includes carpals (wrist bones), metacarpals, and phalanges (finger bones).
Bones of the Foot
- Comprises tarsals (ankle bones), metatarsals, and phalanges (toe bones).
Osteocytes
- Living bone cells that maintain the bone matrix and communicate with other cells.
Osteoclasts Function
- Responsible for bone resorption, breaking down bone tissue.
Osteoblasts Function
- Involved in the formation of new bone and bone mineralization.
Red Bone Marrow
- Produces blood cells, including red blood cells, white blood cells, and platelets.
Yellow Bone Marrow
- Functions primarily in fat storage, serving as an energy reserve.
Cartilage Function
- Acts as a shock absorber in joints and reduces friction during movement.
Types of Joints
- Immovable joints (e.g., skull sutures), slightly movable joints (e.g., vertebrae), and fully movable/synovial joints (e.g., knee, elbow).
Ligaments vs Tendons
- Ligaments connect bone to bone, providing stability to joints.
- Tendons connect muscle to bone, facilitating movement.
Types of Muscle
- Involuntary/smooth muscle (e.g., digestive organs), cardiac muscle (heart), and voluntary/skeletal muscle (controlled through conscious effort).
Voluntary Muscle Function
- Responsible for enabling body movements through contractions.
Antagonistic Muscles
- Muscle pairs that perform opposite actions; for example, the biceps flex the arm while the triceps extend it.
Factors Contributing to Bone Growth
- Influenced by physical activity, hormonal changes, and dietary intake.
Musculoskeletal Disorder Example
- Name a specific disorder and outline its cause, treatment, and prevention strategies (details not provided).
