Study Notes
Main Parts of the Skeletal System
- Bones: Structural support, adults have between 206 and 213 bones.
- Muscles: Over 600 muscles aid in movements such as walking, running, and breathing.
- Cartilage: Strong, flexible tissue acting as a shock absorber in joints.
- Ligaments: Bands of tissue that connect bones to other bones.
- Tendons: Cords connecting muscles to bones.
- Joints: Locations where two bones meet, containing various connective tissues.
Functions of Specific Bones
- Skull: Protects the brain; attachments for facial muscles.
- Cervical Vertebrae: Supports head weight.
- Manubrium Sterni: Facilitates thorax movement.
- Xiphoid Process: Point of muscular attachment.
- Lumbar Vertebrae: Provides stability and muscle attachment.
- Ilium: Alleviates ailments including age-related diseases.
- Sacrum: Forms posterior pelvic walls, stabilizing the pelvis.
- Coccyx: Supports weight for balance when sitting.
- Pubis: Protects intestines, bladder, and reproductive organs.
- Femur: Critical for standing.
- Patella: Protects the knee joint and assists leg movement.
- Tarsal/Tarsus: Key for weight transfer in bipedal locomotion.
- Metatarsus/Metatarsals: Absorbs force and supports during walking.
Importance of the Skeletal System
- Provides body shape and supports organ placement.
- Composed of connective tissues essential for movement and stability.
- Also referred to as the musculoskeletal system.
Functions of the Skeletal System
- Structural Support: Anchors tissue and supports body weight.
- Movement: Joints, connective tissues, and muscles work together in motion.
- Organ Protection: Skull protects the brain, ribs protect the heart and lungs.
- Blood Cell Production: Bone marrow manufactures red and white blood cells.
- Mineral Storage: Bones store essential minerals, like calcium and vitamin D.
Notable Bones and Their Functions
- Phalanges: Enable grip and object handling.
- Orbital Cavity: Protects the eyes while allowing movement.
- Nasal Cavity: Filters and warms air entering the lungs.
- Clavicle: Connects axial and appendicular skeletons with scapula.
- Scapula: Protects upper chest and underlying structures.
- Ribs: Aid in respiration.
- Humerus: Facilitates arm movement and muscle attachments.
- Ulna & Radius: Enable arm and wrist movement.
- Carpals: Allow wrist rotation and movement.
- Metacarpals: Support muscles and tendons in the palm.
- Fibula: Provides ankle stability along with the tibia.
- Tibia: Main load-bearing bone in the leg.
