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.
