Study Notes
Animal Tissues Overview
- Animal tissues are classified into four basic types: epithelial, connective, muscle, and nervous tissue.
- Histology is the study of the microscopic anatomy of cells and tissues.
Epithelial Tissues
- Epithelial tissues cover body surfaces, form glands, and line hollow organs, cavities, and ducts.
- Classification is based on layers (simple vs. stratified) and shape (squamous, cuboidal, columnar).
- Shapes of epithelial cells:
- Simple squamous: single layer of flat cells; functions in diffusion (e.g., alveoli in lungs).
- Simple cuboidal: single layer of cube-shaped cells; involved in secretion and absorption (e.g., kidney tubules).
- Simple columnar: taller cells may have microvilli or cilia; functions in absorption and secretion (e.g., digestive tract).
- Pseudostratified columnar: appears stratified, but all cells contact the basement membrane; common in respiratory tract.
- Stratified squamous: multiple layers for protection against abrasion; found in skin.
- Transitional: cells change shape based on tissue stretch; found in urinary bladder.
Connective Tissues
- Connective tissues are the most abundant and widely distributed, classified as either embryonic or mature.
- Key functions include binding tissues, supporting organs, insulating fat, and transporting substances (e.g., blood).
- Main cell types:
- Fibroblasts: secrete proteins and maintain the extracellular matrix.
- Chondrocytes: produce cartilage.
- Osteocytes: form bone tissue.
- Adipocytes: store fat.
Types of Connective Tissues
- Loose Connective Tissue:
- Areolar tissue: widely distributed, provides cushioning.
- Adipose tissue: stores energy and insulates.
- Reticular tissue: forms a supportive framework for organs (e.g., lymph nodes).
- Dense Connective Tissue:
- Dense irregular: collagen fibers arranged in various directions for multidirectional strength (e.g., dermis).
- Dense regular: collagen fibers aligned; found in tendons and ligaments for unidirectional strength.
- Elastic: contains elastin fibers, allows tissue to stretch (e.g., aorta).
- Cartilage:
- Hyaline: smooth surface for joint movement; found in joints, ribs, and respiratory tract.
- Fibrocartilage: tough, supports heavy loads (e.g., intervertebral discs).
- Elastic: flexible cartilage found in structures like the ear and epiglottis.
- Bone:
- Composed of a calcified matrix; osteocytes develop from chondrocytes as maturity increases.
Muscle and Nervous Tissues
- Muscle and nerve tissues are the final two types of the basic tissue group.
- Neurons and muscle fibers are excitable cells that generate electrical signals (action potentials).
- Types of Muscle Tissue:
- Skeletal: striated, multinucleated, voluntary control; nuclei located peripherally.
- Cardiac: striated, single centrally located nucleus, involuntary; contains intercalated discs and branches.
- Smooth (Visceral): non-striated, involuntary; has a single central nucleus and tapered ends.
Summary of Nerve Function
- Action potentials propagate along neuron and muscle membranes due to voltage-gated ion channels, enabling cell communication and contractions.
