Study Notes
Musculoskeletal System
- The musculoskeletal system is composed of the skeleton and muscles (smooth, skeletal, and cardiac).
- The skeleton provides support, protects internal organs, stores minerals (like calcium).
- Muscles allow movement, protect organs, and help with digestion and nutrient absorption.
- The nervous system coordinates with the musculoskeletal system for movement.
- The skeleton comprises the axial skeleton (skull, spinal column, ribs, sternum) and appendicular skeleton (clavicle, scapula, hip bones, appendages).
- Bones are classified as long (limbs), short (hands/feet), flat (shoulder blades/skull), and irregular (wrists/ankles/face/vertebral column).
Bone Structure
- Bones contain collagen fibers in mineral salts (calcium & phosphorus).
- Compact bone provides strength & protection.
- Spongy bone has bone marrow (red, yellow).
- Red bone marrow creates blood cells (RBCs, WBCs, platelets).
- Yellow bone marrow is fatty tissue.
Joints
- Joints are where bones meet to enable movement.
- Immovable joints (like skull sutures) don't allow movement.
- Gliding joints allow side-to-side and back-and-forth movement (wrist, ankles, vertebrae).
- Pivot joints allow rotation (lower arm bones).
- Hinge joints allow movement in one direction (elbow, knee).
- Ball-and-socket joints allow movement in all directions (shoulder, hip).
Muscles
- Muscles work in pairs to allow movement (e.g., biceps & triceps).
- Muscles contract (shorten) and relax.
- Muscles are made of muscle fibers.
- Types of muscles include skeletal (voluntary), smooth (involuntary), and cardiac (involuntary in the heart).
- Tendons attach muscles to bones.
Integumentary System
- The integumentary system is the skin, hair, nails, and glands.
- The skin protects, regulates temperature, detects sensations, stores water/fat, produces vitamin D, and removes waste.
- The skin has layers including epidermis (outer) and dermis (inner).
- Melanin gives skin color and protects against UV radiation.
- Sweat helps regulate body temperature.
- The skin has sensory receptors to detect stimuli like touch, pressure, temperature, and pain.
Digestive System
- The digestive system breaks down food to absorb nutrients.
- Mechanical digestion (chewing) breaks food into smaller pieces.
- Chemical digestion uses enzymes to break down large molecules (carbohydrates, proteins, lipids).
- The digestive system includes the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus.
- Enzymes (e.g., salivary amylase) break down food in different parts of the system.
- Nutrients are absorbed in the small intestine.
- Undigested material is eliminated through the anus.
