Study Notes
Skeletal System Overview
- The skeletal system is comprised of all bones and tissues like tendons, ligaments, and cartilage that connect them.
- Babies are born with around 300 bones, but these fuse to form the 206 bones in adults.
- The skeletal system has crucial functions including protection, support, movement, shaping the body, producing blood cells, and storing minerals.
Functions of the Skeletal System
- Protection: The skull protects the brain and eyes; the rib cage safeguards the heart and lungs; and the vertebrae protect the spinal cord.
- Support: The skeletal system provides structural support for the entire body.
- Movement: Muscles work with bones via tendons; bones connect to each other using ligaments, creating joints.
- Shape: The skeleton defines the body's shape and form.
- Blood Production: Bone marrow, located within some bones, creates blood cells.
- Mineral Storage: Bones store calcium and phosphorus, releasing them when the body needs them.
Bone Composition
- Bones are made of compact and spongy bone tissue.
- Compact bone forms the hard, protective outer shell of all bones.
- Spongy bone, located within the compact bone, is highly porous and provides flexibility.
- Bone tissue contains several cell types embedded in organic salts (mostly calcium and phosphorus) for strength, and collagen fibers granting flexibility.
Bone Tissues
- Bone marrow, endosteum, periosteum, nerves, blood vessels, and cartilage are all tissues found within bones.
Divisions of the Skeletal System
- The two main categories are the axial and appendicular skeletons.
- Axial Skeleton: Forms the central axis of the body, comprising the skull, vertebral column, ribs, and sternum.
- Appendicular Skeleton: Comprises bones related to the appendages (limbs) of the body, including the upper limbs (arms) and lower limbs (legs), as well as the shoulder and pelvic girdles.
Axial Skeleton
- Skull: A bony structure protecting the brain and the face. It consists of 8 cranial and 14 facial bones.
- Vertebral Column: A series of 33 irregular-shaped vertebrae (bones) arranged in five groups: Cervical, Thoracic, Lumbar, Sacral, and Coccygeal. These support the spinal cord and structure the back of the body.
- Ribs: 24 curved, flat bones formed into 12 pairs, protecting vital organs. They can be classified as true (1-7), false (8-10), or floating (11-12).
- Sternum: A flat, dagger-shaped bone in the center of the chest, forming part of the rib cage, protecting internal organs. This is where the first 7 pairs (true) ribs connect.
Appendicular Skeleton
- Upper Limbs: The arms, composed of the humerus (upper arm bone), radius and ulna (forearm bones), carpals (wrist bones), metacarpals (hand bones), and phalanges (finger bones).
- Lower Limbs: The legs, including the femur (thigh bone), tibia and fibula (leg bones), tarsals (ankle bones), metatarsals (foot bones), and phalanges (toe bones).
- Shoulder Girdle: Made up of two clavicles (collarbones) and two scapulae (shoulder blades).
- Pelvic Girdle: Comprised of two coxal bones (hip bones), which connect the lower limbs to the axial skeletal system.
Types of Bones
- Long Bones: Longer than wide (e.g., femur, humerus), supporting the body weight.
- Short Bones: Roughly cube-shaped (e.g., wrist and ankle bones), offering stability.
- Irregular Bones: Varied shape (e.g., vertebrae, facial bones), exhibiting varied functions.
- Flat Bones: Thin, flat plates (e.g., skull bones, ribs), providing protection or muscles attachments.
- Sesamoid Bones: Embedded in tendons (e.g., patella). They modify pressure and reduce friction.
Diseases
- Osteoporosis: Reduced bone density and quality, leading to increased bone fragility and fracture risk. Risk factors include aging, lack of hormones, genetics. Symptoms include back pain, height loss, bent posture, and ease of breaking bones. Treatments include calcium rich foods, vitamin D, exercise, avoiding alcohol and smoking.
- Arthritis: Inflammation of the joints. Types include gout and rheumatoid arthritis. Causes may vary from reductions in cartilage to immune system attacks. Symptoms include pain, reduced joint function, stiffness, swelling, redness, and joint tenderness. Treatments may include surgery, home remedies, medications, and in some cases, weight reduction.
- Scoliosis: Abnormal curve in the spine or backbone. Causes include birth defects, child growth, aging, injury, or prior spinal surgery. Symptoms include uneven shoulders, uneven hips, a rotating spine, back pain, and difficulty breathing. Treatments vary by severity, including bracing or surgical operation.
