Study Notes
Musculoskeletal Disorders
-
Types:
- Osteoarthritis (degenerative joint disease)
- Rheumatoid Arthritis (autoimmune disorder)
- Osteoporosis (bone density loss)
- Fibromyalgia (chronic pain syndrome)
-
Causes:
- Genetics
- Injury
- Infection
- Poor posture
-
Symptoms:
- Pain
- Inflammation
- Stiffness
- Limited mobility
Osteology
-
Study of:
- Bones (structure, function, development)
- Skeletal system
-
Importance:
- Supports body structure
- Protects internal organs
- Facilitates movement
-
Bone Types:
- Long bones (e.g., femur, humerus)
- Short bones (e.g., carpals, tarsals)
- Flat bones (e.g., ribs, sternum)
- Irregular bones (e.g., vertebrae, pelvis)
Joint Types
-
Types:
-
Synovial Joints:
- Moveable (e.g., elbow, knee)
- Allow for flexibility and motion
-
Cartilaginous Joints:
- Partially moveable (e.g., spine)
- Allow for limited motion
-
Fibrous Joints:
- Immoveable (e.g., skull bones)
- Allow for no motion
-
Synovial Joints:
-
Joint Structure:
- Articular cartilage (covers bone ends)
- Synovial fluid (lubricates joint)
- Ligaments (connect bones)
Skeletal System
-
Functions:
- Supports body structure
- Protects internal organs
- Facilitates movement
- Produces blood cells
-
Divided into:
- Axial skeleton (skull, spine, ribcage)
- Appendicular skeleton (upper and lower limbs)
-
Bone Functions:
- Support
- Protection
- Movement
- Blood cell production
- Storage of minerals (e.g., calcium)
Bone Structure
-
Tissue Types:
-
Compact Bone:
- Dense, compact tissue
- Forms outer layer of bone
-
Cancellous Bone:
- Spongy, porous tissue
- Forms inner layer of bone
-
Compact Bone:
-
Bone Cells:
- Osteoblasts (produce bone tissue)
- Osteoclasts (resorb bone tissue)
- Osteocytes (maintain bone tissue)
-
Bone Matrix:
- Organic component (collagen fibers)
- Inorganic component (hydroxyapatite crystals)
Musculoskeletal Disorders
- Osteoarthritis is a degenerative joint disease
- Rheumatoid Arthritis is an autoimmune disorder
- Osteoporosis is a condition of bone density loss
- Fibromyalgia is a chronic pain syndrome
Causes of Musculoskeletal Disorders
- Genetic factors can contribute to musculoskeletal disorders
- Injuries can lead to musculoskeletal disorders
- Infections can cause musculoskeletal disorders
- Poor posture can contribute to musculoskeletal disorders
Symptoms of Musculoskeletal Disorders
- Pain is a common symptom of musculoskeletal disorders
- Inflammation can occur in musculoskeletal disorders
- Stiffness is a common symptom of musculoskeletal disorders
- Limited mobility can result from musculoskeletal disorders
Osteology
- Osteology is the study of bones, including their structure, function, and development
- The skeletal system is comprised of bones and their associated tissues
- The skeletal system provides structural support for the body
- The skeletal system protects internal organs
- The skeletal system facilitates movement
Bone Types
- Long bones, such as the femur and humerus, are characterized by their length
- Short bones, such as the carpals and tarsals, are cube-shaped
- Flat bones, such as the ribs and sternum, are thin and flat
- Irregular bones, such as the vertebrae and pelvis, have complex shapes
Joint Types
- Synovial joints are moveable and allow for flexibility and motion
- Cartilaginous joints are partially moveable and allow for limited motion
- Fibrous joints are immoveable and allow for no motion
Joint Structure
- Articular cartilage covers the ends of bones in a joint
- Synovial fluid lubricates the joint and reduces friction
- Ligaments connect bones and provide stability to the joint
Skeletal System
- The skeletal system provides structural support for the body
- The skeletal system protects internal organs
- The skeletal system facilitates movement
- The skeletal system produces blood cells
- The skeletal system is divided into the axial skeleton and appendicular skeleton
Bone Functions
- Bones provide support for the body
- Bones protect internal organs
- Bones facilitate movement
- Bones produce blood cells
- Bones store minerals, such as calcium
Bone Structure
- Compact bone is a dense, compact tissue that forms the outer layer of bone
- Cancellous bone is a spongy, porous tissue that forms the inner layer of bone
- Osteoblasts produce bone tissue
- Osteoclasts resorb bone tissue
- Osteocytes maintain bone tissue
- The bone matrix is composed of organic and inorganic components
