Types of Animal Tissues Quiz

Epithelial Tissue
- Covers body surfaces and lines cavities.
- Functions: protection, absorption, secretion, and sensation.
- Types:
  - Simple (single layer) and stratified (multiple layers).
  - Shapes: squamous (flat), cuboidal, and columnar.
Connective Tissue
- Supports, binds together, and protects tissues and organs.
- Characteristics: abundant extracellular matrix.
- Types:
  - Loose connective tissue (e.g., adipose and areolar tissue).
  - Dense connective tissue (e.g., tendons and ligaments).
  - Specialized connective tissues (e.g., cartilage, bone, blood).
Muscle Tissue
- Responsible for movement.
- Types:
  - Skeletal muscle: voluntary, striated, multi-nucleated.
  - Cardiac muscle: involuntary, striated, single nucleus; found in the heart.
  - Smooth muscle: involuntary, non-striated, single nucleus; found in walls of hollow organs.
Nervous Tissue
- Composed of neurons and glial cells.
- Functions: transmission of electrical signals and support.
- Neurons: specialized cells that transmit impulses.
- Glial cells: support and protect neurons.

Epithelial Tissue:
- Protects against abrasion and pathogens.
- Facilitates diffusion, filtration, and secretion.
Connective Tissue:
- Provides structural support and elasticity.
- Stores energy (e.g., adipose tissue).
- Transports substances (e.g., blood).
Muscle Tissue:
- Enables voluntary (skeletal) and involuntary (smooth and cardiac) movements.
Nervous Tissue:
- Regulates body functions through nerve impulses.
- Processes and communicates information throughout the body.

Cellularity:
- Epithelial tissues are densely packed; connective tissues have more matrix.
Polarity:
- Epithelial tissues have an apical (top) surface and a basal (bottom) surface.
Regeneration:
- Epithelial tissues have a high regenerative capacity; connective tissue varies.
Extracellular Matrix:
- Vital for connective tissues, provides structural and biochemical support.

Covers the body's surfaces and lines cavities.
Functions:
- Protection from abrasion and pathogens.
- Facilitates diffusion, filtration, and secretion.
- Sensation
Types:
- Simple: single layer of cells.
- Stratified: multiple layers of cells.
Shapes:
- Squamous: flat and thin.
- Cuboidal: cube-shaped.
- Columnar: tall and column-like.

Supports, binds together, and protects tissues and organs.
Characterized by abundant extracellular matrix: a non-living material surrounding cells.
Types:
- Loose connective tissue:
  - Adipose tissue: stores fat for energy.
  - Areolar tissue: provides support and flexibility.
- Dense connective tissue:
  - Tendons: connect muscle to bone.
  - Ligaments: connect bone to bone.
- Specialized connective tissues:
  - Cartilage: provides support and flexibility.
  - Bone: provides strength and support.
  - Blood: transports oxygen, nutrients, and waste products.

Composed of neurons and glial cells.
Functions:
- Transmission of electrical signals.
- Support and protection of neurons.
Neurons:
- Specialized cells that transmit impulses (electrical signals).
- Communicate with other neurons, muscles, and glands.
Glial cells:
- Support and protect neurons.
- Do not transmit electrical signals.

Cellularity:
- Epithelial tissues are densely packed with cells.
- Connective tissues have more extracellular matrix than cells.
Polarity:
- Epithelial tissues have an apical (top) surface and a basal (bottom) surface.
- These surfaces often have different structures and functions.
Regeneration:
- Epithelial tissues have a high regenerative capacity; they quickly replace damaged cells.
- Connective tissue varies in its regenerative capacity.
Extracellular Matrix:
- Vital for connective tissues.
- Provides structural and biochemical support.
- Consists of fibers (collagen, elastin, reticular) and ground substance (fluid, proteins, carbohydrates).
