Study Notes
Muscle System
- Muscular atrophy: decrease in size and wasting of muscle tissue, can occur due to loss of nerve supply, and is common with aging (20-40% muscle loss and strength reduction).
- Flexor: muscle that bends a joint and brings a limb closer to the body.
- Extensor: muscle that straightens a joint and brings a limb away from the body.
Smooth Muscle
- Non-striated, involuntary muscles without striations.
- Do not require direct nerve stimulation to operate.
- Found in the walls of hollow organs, such as the digestive tract.
Muscular Dystrophy
- A group of genetic diseases causing progressive weakness and degeneration of skeletal muscles.
- Over 30 types, varying in age of onset, severity, and affected muscles.
- Duchenne muscular dystrophy (DMD): one of the most severe forms, inherited, and the most common hereditary neuromuscular disease.
Organ Systems

- Reproductive System
- Excretory System
- Nervous System
- Endocrine System
Skin Diseases and Disorders
- Acne: clogged or plugged hair follicles, resulting in red bumps on the skin.
- Bacterial infections: skin infections caused by bacteria.
- Birthmarks: areas of discolored and/or raised skin present at birth or within a few weeks of birth.
- Eczema and Hives: itchy skin rashes related to allergies.
- Fungal infections: skin diseases caused by fungi.
- Skin cancer
- Viral infection
Skeletal System
- Axial skeleton: formed by the bones of the head, neck, and trunk (80 bones).
- Appendicular skeleton: formed by the bones of the arms and legs.
- Ligaments: strong bands of flexible tissue that hold bones together.
Disorders of Skeletal System
- Arthritis: inflammation of the joints.
- Bone Cancer
- Bursitis
- Kyphosis
- Leukemia
- Osteoporosis
- Poliomyelitis
- Scoliosis
- Spina bifida
- Talipes equinovarus (clubfoot)
