Study Notes
The Skeletal System
- Cartilage: Found in the epiphyseal plate, outer ear, epiglottis, but not the inner layer of arteries
- Body Cavities: The diaphragm separates the thoracic cavity from the abdominal cavity
-
Muscular Contraction:
- Nerve impulses trigger muscle contractions
- Actin filaments slide past myosin filaments
- Myosin heads pull on actin filaments, causing contraction
- Flexor vs. Extensor Muscles: Flexor muscles bend a limb; Extensor muscles straighten a limb.
- Axial and Appendicular Skeletons: Both skeletons contain red bone marrow
- Semimovable Joints: Allow bending and twisting, as found between vertebral bones
- Rheumatoid Arthritis: An autoimmune disease that causes inflammation, swelling, stiffness, and deformity of joints.
The Circulatory System
- Circulatory System Functions: Transports nutrients, hormones, and gases; helps maintain body temperature; returns fluids to the bloodstream
- Heart Valves: Valves in the heart prevent blood from flowing backward
- Pulmonary Circulation: The pulmonary artery carries deoxygenated blood from the heart to the lungs.
- Blood Components: Plasma, red blood cells, white blood cells, platelets
- Blood Types: Individuals with type A blood and B anti-Rh antibodies can donate to individuals with type AB- blood.
- Hemoglobin: Each hemoglobin molecule can carry 4 oxygen molecules.
The Immune System
- Nonspecific Defenses: Stomach acids, mucus, and waxes are nonspecific defenses; cytokines are specific defenses.
- Interferon: A protein released by virus-infected cells to warn other cells and activate immune responses.
