Study Notes
Basic Tissue Types
- Tissue consists of a group of cells with similar structures and functions.
- Epithelial tissue has closely packed cells with no intercellular spaces.
- Connective tissue includes:
- Loose Areolar: Contains fibroblasts, fat cells, mast cells, and macrophages, separated by elastic and collagen fibers.
- Adipose Tissue: Specializes in fat storage.
- Dense Connective Tissue: Densely packed collagen fibers, strong but poorly vascularized.
Types of Cartilage
- Hyaline Cartilage: Composed of small groups of cells, found in long bones, larynx, and bronchi.
Blood Cells
- White Blood Cells (Leukocytes): Crucial for immune response.
Histology
- The study of tissues.
Anatomical Terminology
- Prone: Face-down orientation.
- Antebrachium: Refers to the forearm region.
- Superior: Position above another (e.g., neck to knees).
- Distal: Farther from the point of attachment (e.g., wrist to elbow).
Medical Imaging Techniques
- X-ray: High-energy radiation used to penetrate solids.
- CT Scan: Analyzes cross-sectional X-rays for detailed body structure imaging.
- MRI: Uses magnetic fields and radio waves to produce detailed images of soft tissues.
- PET Scan: Utilizes radio pharmaceuticals to detect metabolic processes in the body.
Organismal Characteristics
- Organization: Interrelationship of individual parts from cells to organs.
- Metabolism: Energy use for growth, movement, and reproduction.
- Responsiveness: Adaptation to environmental changes.
- Growth: Increase in organism size.
- Development: Changes over time.
- Reproduction: Formation of new cells and organisms.
- Homeostasis: Maintenance of stable internal conditions.
Homeostatic Regulation
- Controlled primarily by the nervous and endocrine systems.
- Disruptions can be caused by external (e.g., heat) and internal stimuli (e.g., stress).
-
Feedback Systems:
- Negative Feedback: Reverses changes to maintain stability (e.g., temperature regulation).
- Positive Feedback: Intensifies changes, leading to growth or processes like blood clotting during childbirth.
Proteins and Enzymes
- Proteins: Chief structural component, forming hormones and enzymes.
-
Types of Proteins:
- Fibrous Proteins: Long fibers (e.g., keratin in hair).
- Globular Proteins: Spherical shape (e.g., hemoglobin).
- Conjugated Proteins: Combination with other molecules (e.g., glycoproteins).
Nucleic Acids
- Consist of carbon, hydrogen, oxygen, nitrogen, and phosphorus.
- Building blocks are nucleotides.
Cell Biology
- Organelles: Small structures within cells (e.g., nucleus, mitochondria, ribosomes).
- Mitochondria: Energy production through cellular respiration.
-
Cell Cycle: Stages of cell growth and division:
- Interphase (G1, S, G2) prepares for mitosis, which includes Prophase, Metaphase, Anaphase, and Telophase.
Anatomy and Physiology
- Anatomy: Study of body structures.
- Physiology: Study of body functions.
Tissue Types in Detail
- Simple Squamous Epithelium: Thin single layer for gas exchange (lungs).
- Simple Cuboidal Epithelium: Cube-shaped cells for secretion/absorption (kidneys).
- Stratified Squamous Epithelium: Multiple layers for protection (skin).
- Transitional Epithelium: Stretches and returns to shape (urinary bladder).
Major Cell Types and Function
- Fibroblasts: Common in connective tissue, secrete fibers.
- Macrophages: Scavenger cells for defense.
- Mast Cells: Release heparin and histamine for inflammation.
Major Organ Systems
- Integumentary System: Protection.
- Skeletal System: Support and movement.
- Muscular System: Maintains posture and facilitates movement.
