Study Notes
Key Terms in A&P
- Anatomy studies body structure and interrelationships.
- Physiology examines how body parts function to sustain life.
- Principle of complementarity: the structure of a body part determines its function.
Subdivisions of Anatomy
- Gross Anatomy: Focuses on large-visible structures; includes regional, systemic, and surface anatomy.
- Microscopic Anatomy: Studies structures not visible to the naked eye, divided into cytology (cells) and histology (tissues).
- Developmental Anatomy: Observes anatomical and physiological changes throughout life, including embryology (development before birth).
Levels of Organization
- Layers from chemical to organism level: Chemical, Organelle, Cellular, Tissue, Organ, System, Organism.
Cellular Structure
- Components of a cell include centrioles, ribosomes, plasma membrane, endoplasmic reticulum, Golgi apparatus, lysosomes, mitochondria, nucleus, peroxisomes, proteasomes, and cytoplasm which consists of cytosol and a cytoskeleton.
Cellular Membrane Transport
- Passive Transport: Includes diffusion (simple, facilitated, osmosis) and filtration (no energy required).
- Active Transport: Requires energy; includes active transport, vesicular transport (endocytosis, phagocytosis, pinocytosis, exocytosis).
Cellular Metabolism
- Metabolism consists of anabolism (building large molecules, energy-consuming) and catabolism (breaking down molecules, energy-releasing).
- Enzymes lower activation energy for reactions; they regulate cell metabolism.
Cell Growth and Reproduction
- Mitosis produces two identical diploid cells; meiosis produces four haploid, genetically diverse cells.
Tissue Types
- Types of tissues: Epithelial, Connective, Nerve, Muscle.
Epithelial Tissue
- Covers body surfaces/cavities; functions in protection, absorption, filtration, excretion, secretion, sensory reception.
- Types: Surface/lining (squamous, cuboidal, columnar) and glandular epithelium (endocrine and exocrine).
Connective Tissue
- Functions include binding/support, protection, insulation, storage, and transportation.
- Contains abundant intercellular substance; classified into four types: connective tissue proper, cartilage, bone, blood.
Muscle Tissue
- Highly vascularized; responsible for movement.
- Three types: Skeletal (voluntary), Cardiac (involuntary, heart), Smooth (involuntary, organs).
Nervous Tissue
- Main component of the nervous system; consists of neurons and supporting cells (neuroglia).
- Regulates body functions; divided into CNS (central) and PNS (peripheral).
Integumentary System
- Comprises skin, hair, nails, glands; functions: protection, temperature regulation, sensation, metabolic processes.
- Epidermis (avascular epithelial tissue) and dermis (vascular connective tissue); skin pigmentation due to melanin.
Skeletal System
- Major functions: support, protection, movement, mineral storage, blood cell formation, fat storage, hormone production.
- Composed of 206 named bones, classified into axial (80 bones) and appendicular skeletons.
Blood and Cardiovascular System
- Blood functions: transport, regulation, and protection.
- Components: plasma, formed elements (RBCs, WBCs, platelets).
- Heart rate and stroke volume are key measurements in cardiovascular health.
Lymphatic System
- Composed of lymphatic vessels, lymph fluid, lymph nodes; returns fluids to blood and plays a key role in immunity.
- Lymphoid organs include spleen, thymus, tonsils; T and B cells mature in specific locations.
Immune System
- Two types: Innate (nonspecific) and Adaptive (specific).
- Involves a variety of responses against pathogens, employing mechanical barriers, phagocytes, and lymphocytes.
Respiratory System
- Functions: supply O2, dispose of CO2 through pulmonary ventilation, external respiration, transport, and internal respiration.
- Major organs: nose, nasal cavity, pharynx, larynx, trachea, bronchi, lungs.
Digestive System
- Main functions: ingestion, digestion, absorption, excretion.
- Comprises two groups: alimentary canal (GI tract) and accessory organs (teeth, tongue, liver, pancreas).
