Study Notes
The Skeleton System
- The skeleton is the central structure of the body, composed of bones, joints, and cartilage.
- It provides a framework for muscles to attach, giving us our human shape.
- The human skeleton contains 206 bones, with 6 tiny bones in the middle ear that function in hearing.
- The largest bone in the body is the femur (thigh bone).
- Bones are strong but light, with lots of air under the surface, and store minerals needed by the body.
4 Functions of the Skeleton
- Support: Provides a framework to support the organs and tissues of the body.
- Protection: Protects internal organs, such as the brain, heart, lungs, and other viscera.
- Movement: Provides a framework for muscles to attach, allowing for movement through muscle contraction.
- Supply & Storage: A source of red blood cells (transport oxygen) and white blood cells (fight infection) formed within the bone marrow.
Types of Bones
- Long Bones: Longer than they are wide, examples include femur, humerus, and bones of fingers and toes.
- Short Bones: Equal proportions, roughly shaped like a cube, examples include bones of wrists and ankles.
- Curved Bones: Thin and slightly curved, examples include skull, scapula, and ribs.
- Curved bones protect internal organs, attach muscles to bones, and provide stability to joints.
Functions of Important Bones
- Skull: Forms the head, supports face structures, forms a cavity for the brain, and protects the brain from injury.
- Ribs: Protects internal organs, provides support, and aids in respiration.
- Spine: Protects the spinal cord, provides stiffening for the body, and attaches to pectoral and pelvic girdles.
The Human Skeleton
- The legs support and bear the weight of the upper body, and allow for daily activities.
- The bones that make up the fingers and toes are called phalanges.
- The femur is the longest and strongest bone in the human skeleton, and articulates with the acetabulum in the pelvic bone to form the hip joint.
Types of Muscle
- Smooth Muscle: Involuntary, found in internal organs, causes movements within the body.
- Cardiac Muscle: Involuntary, found only in the heart.
- Skeletal Muscle: Voluntary, attached to bones, controls movement.
Types of Movement
- Flexion: Bending a joint, decreasing the angle of the joint.
- Extension: Straightening a joint, increasing the angle of the joint.
Functions of Muscles
- Traps: Allows for head movement, helps with upper back lifting.
- Shoulders: Allows for overhead lifting, arm rotation.
- Chest: Controls arm movement, pushes open doors, aids in inhalation.
- Biceps: Helps with curling motion, flexing the elbow, controls shoulder and elbow.
- Triceps: Contracts to straighten the arm, extends the elbow, counteracts biceps action.
- Lats: Allows for support, sitting up, tilting the pelvis, bending the lower spine, aids in breathing and posture.
- Glutes: Allows for leg movement, prevents knee buckling, aids in squats, climbing stairs, standing, and walking.
- Hamstrings: Allows for knee and hip movement, prevents knee buckling, aids in running, jumping, and squatting.
- Calves: Helps with ankle movement, curling toes, bending the knee.
