Study Notes
Organization of the Human Body
- Anatomy: Studies internal and external structures of the body.
- Physiology: Focuses on body functions; structure relates to function.
- Levels of organization include cells, tissues, organs, systems, and the organism.
Body Systems
- Integumentary System: Comprises skin, hair, glands, and nails.
- Skeletal System: Includes bones, cartilage, ligaments, and tendons.
- Nervous System: Consists of the brain and spinal cord.
- Muscular System: Contains smooth, skeletal, and cardiac muscles.
- Cardiovascular/Circulatory System: Made up of the heart, blood vessels, and blood.
- Respiratory System: Contains the lungs, trachea, and airways.
- Lymphatic System: Comprises glands, lymph vessels, nodes, and ducts.
- Endocrine System: Includes pancreas, thyroid, and gonads.
- Digestive System: Encompasses the stomach, mouth, intestines, and anus.
- Reproductive System: Comprises uterus, penis, vagina, and testicles.
- Urinary System: Contains kidneys, bladder, and urethra.
Autopsy
- Post Mortem Examination: Involves dissection to determine the cause of death.
Biological Processes
- Catabolism: Breakdown of complex molecules into simpler ones (e.g., proteins to amino acids).
- Anabolism: Synthesis of complex molecules from simpler ones (e.g., muscle growth).
Live Processes
- Maintain health by regulating body temperature, blood pressure, and nutrient levels.
Clinical Terms
- Disorder: Abnormality of structure or function.
- Disease: Specific illness characterized by signs and symptoms; subjective (e.g., anxiety) vs. objective (e.g., asthma).
Aging and Homeostasis
- Aging affects homeostasis, influencing body temperature and blood pressure.
Feedback Systems
- Negative Feedback Systems: Reverse changes to maintain stability in controlled conditions (e.g., lowering high blood pressure).
- Positive Feedback Systems: Amplify changes, requiring external factors to terminate (e.g., labor contractions).
Anatomical Terms
- Define body positions using standardized terms related to direction and location.
- Divided into quadrants: Right Upper Quadrant (RUQ), Left Upper Quadrant (LUQ), Right Lower Quadrant (RLQ), Left Lower Quadrant (LLQ).
Cells: Parts & Functions
- Cell Membrane: Regulates interactions between the cell and its environment.
- Intracellular Fluid (ICF): Fluid within the cell.
- Extracellular Fluid (ECF): Fluid outside the cell.
Principles of Diffusion
- Diffusion: Passive process driven by kinetic energy; moves from high to low concentration.
- Types of diffusion include Simple Diffusion, Facilitated Diffusion, and Osmosis (water movement).
Cellular Components
- Lysosomes: Contain enzymes for digestion; can lead to diseases like Tay-Sachs.
- Peroxisomes: Detoxify substances, abundant in the liver.
- Mitochondria: Powerhouse of the cell, generating ATP through cellular respiration.
- Nucleus: Contains DNA, responsible for transcription (mRNA synthesis).
Protein Synthesis
- Translation occurs at ribosomes using mRNA and tRNA for amino acid assembly.
Cell Division
- Mitosis: Process resulting in two identical cells; consists of phases: Prophase, Metaphase, Anaphase, and Telophase.
- Cytokinesis: Division of cytoplasm following mitosis.
Cellular Diversity
- Different cell types have unique structures based on function (e.g., sperm cells' flagellum for motility).
Aging
- Progeria: Rapid aging syndrome with significant health issues; life expectancy is around 13 years.
- Werner Syndrome: Adult form of progeria; typically leads to death before age 50.
Tissue Characteristics
- Histology: Study of tissues; classified into four basic types.
- Epithelial Tissue: Covers surfaces; categorized by layers (simple vs. stratified) and shape (squamous, cuboidal, columnar).
Bone and Connective Tissues
- Bone Tissue: Classified as compact or spongy; spongy bone contains trabeculae.
- Liquid Connective Tissue: Includes blood and lymph.
Body Membranes
- Four types: Mucous, Serous, Cutaneous, and Synovial.
- Each type serves distinct functions, from lubrication to coverage.
Muscle and Nervous Tissue
- Three types of muscle: Skeletal (voluntary), Cardiac (involuntary), Smooth (involuntary).
- Neurons: Conduct nerve impulses; Neuroglia: Support nervous tissue.
Tissue Repair
- Healing capacity varies; affected by factors like age and type of tissue.
Anabolic Steroids
- Used for muscle strength enhancement but linked to severe health risks (e.g., liver cancer, mood swings).
Atrophy
- Refers to the wasting away of tissue; commonly due to lack of use.
IM Injection Sites
- Common sites include the dorsogluteal and ventrogluteal regions for deep muscle injection.
