Study Notes
Histo-logy Overview
- Histo- = tissue; -logy = study; histology studies tissues' structure and function.
Tissue Types
- Tissues are groups of similar origin cells that perform a common function.
- Four basic types of tissues aim to carry out specialized activities.
Epithelial Tissue
- Comprises surface epithelium and glandular epithelium; involved in protection, secretion, and absorption.
- Surface epithelium includes various styles:
- Simple squamous, cuboidal, nonciliated columnar, ciliated columnar, pseudostratified columnar, stratified squamous, stratified cuboidal, stratified columnar, and transitional.
- Glandular epithelium categorized into:
- Endocrine glands (hormonal secretion) and exocrine glands (secretion to surfaces).
Connective Tissue
- Functions include binding cells, storing water, medium for substance exchange, and protective roles.
- Components consist of:
- Extracellular fibers (e.g., collagen) and connective tissue cells (e.g., fibroblasts).
- Loose connective tissue types:
- Areolar: Packing material found almost throughout the body, offers strength and elasticity.
- Adipose: Stores fat, provides insulation and cushioning.
- Reticular: Provides supporting framework for organs and immune functions.
Membranes
- Various membranes include serous (lines body cavities) and synovial (lines joints).
- Serous membranes consist of mesothelium (simple squamous) and secrete serous fluid to reduce friction.
Nervous Tissue
- Composed of neurons and supporting cells.
- Neurons consist of:
- Cell body: Contains the nucleus; controls functions.
- Dendrites: Projections that receive information from other neurons.
- Axon: Long projection that transmits impulses from the neuron to other cells.
Key Concepts
- Cell junctions crucial for tissue function:
- Tight, adherens, desmosomes, hemidesmosomes, and gap junctions facilitate communication and structural integrity.
- Mesenchyme serves as the precursor for all connective tissues during early development.
- Connective tissues can vary in composition (e.g., lymph is liquid connective tissue with less protein than blood).
General Functionality
- Each tissue type plays a role in maintaining homeostasis, facilitating body function, and responding to environmental changes.
