Study Notes
Hebrews 13:8
- Jesus Christ is the same yesterday, today, and forever.
Chapter 1: Anatomy and Physiology
- Anatomy: The study of the structure and shape of the human body.
- Physiology: The study of the function of the human body.
-
Levels of Structure:
- Chemical/Molecular
- Cellular
- Tissue
- Organ
- Organ System
- Organism
- Urinary System: Eliminates metabolic waste and nitrogenous waste.
- Anatomical Position: Standard body position used for anatomical descriptions.
-
Body Regions:
- Deltoid (shoulder)
- Umbilical (naval)
- Abdominal (anterior body trunk below ribs)
- Tarsal (ankle)
- Fibular (lateral part of leg)
- Orbital (eye area)
- Inguinal (thigh meeting body trunk)
- Body Planes: Three imaginary planes used to section the body.
-
Directional Terms:
- Inferior (below)
- Posterior (backside)
- Lateral (away from midline)
- Deep (internal)
- Distal (farther from origin)
Chapter 3: Tissues
-
Connective Tissues:
- Dense CT
- Adipose (fat)
- Blood
- Epithelial Tissue: Found in body coverings, linings, and glands.
- Extracellular Matrix: Only found in connective tissue.
- Tendons: Connective tissue attaching bone to muscle.
- Subcutaneous Tissue: Adipose tissue beneath the skin.
- Blood Vessels: Contains both Dense CT and blood.
- Active vs. Passive Transport: Both move molecules across membranes, but active requires energy and passive does not.
-
Mitosis Stages:
- Prophase: Centrioles split, move to ends
- Metaphase: Chromosomes align
- Anaphase: Chromosomes separate
- Telophase: Chromosomes move to poles
-
Tissue Functions:
- Epithelial: Protection, absorption, filtration, secretion
- Connective: Connects body parts, widespread, well-vascularized (except tendons/ligaments)
- Nervous: Irritability and conductivity (responds to stimuli)
- Muscle: Contraction for movement
Chapter 4: Membranes and Skin
-
Epithelial Membranes:
- Cutaneous (skin)
- Mucous (lines cavities open to exterior)
- Serous (lines closed cavities)
-
Skin Functions:
- Vitamin D synthesis
- Protection (mechanical, chemical, thermal, UV, bacteria)
- Water resistance (keratin)
- Body temperature regulation
- Epidermis Cells: Keratinocytes
- Melanins Effect: Increases in sun tanning; defense mechanism for rebuilding skin cells.
- Avascular Layer: Stratum corneum (epidermis).
- Nutrient Delivery: Nutrients diffuse from dermis to epidermis.
- Acne Cause: Sebaceous glands (oil glands) disorder within the dermis
- Papillary Layer: Thin, superficial dermis layer directly under epidermis, providing nutrient supply to epidermis.
- Fingernails/Toenails: Epidermal modifications.
- Apocrine Glands: Open into hair follicles and are associated with the surface of the skin.
- Sebaceous Glands: Secrete oil.
-
Burn Complications:
- First threat: Dehydration
- Second Threat: Infection
- Burn Estimation: Rule of nines.
Chapter 5: Skeletal System
-
Bone Functions:
- Support
- Protection
- Movement
- Storage (minerals, fat)
- Blood cell formation
-
Bone Classifications:
- Long (femur)
- Short (carpals)
- Flat (skull)
- Irregular (vertebrae)
-
Joints:
- Plane (wrist)
- Pivot (ulna/radius)
- Hinge (elbow)
- Condyloid (knuckles)
- Saddle (thumb)
- Ball and Socket (hip, shoulder)
Chapter 6: Muscular System
-
Muscle Functions:
- Movement
- Posture
- Stabilize joints
- Generate heat
-
Muscle Anatomy:
- Epimysium (covers entire muscle)
- Perimysium (covers fascicle)
- Endomysium (covers single fiber)
-
Muscle Types:
- Skeletal (attached to bone)
- Cardiac (heart only)
- Smooth (digestive tract, blood vessels)
- Neuromuscular Junction: Site where nerve meets muscle.
- Sarcomere: Contractile unit of muscle fiber.
-
Sliding Filament Theory:
- Myosin heads attach to actin.
- Power stroke (movement) occurs.
- Cross-bridges detach.
- ATP causes detachment, followed by another attachment further along actin.
- Repeating cycle shortens muscle.
-
Muscle Contraction Process:
- Nerve impulse releases Acetylcholine.
- Depolarization occurs, releasing Ca+ from sarcoplasmic reticulum.
- Ca+ binds to troponin, moving tropomyosin.
- Myosin attaches to actin.
- ATP breakdown releases energy for power stroke.
- Myosin detaches and repeat.
- Relaxation occurs when Ca+ is pumped back.
