Study Notes
Animal Tissues
- Animal tissues are groups of connected cells that work together to perform specific functions in an animal.
Types of Tissues
- Epithelial tissue: Covers body surfaces and lines body cavities.
- Muscle tissue: Enables movement.
- Nerve tissue: Facilitates communication.
- Connective tissue: Supports, connects, or separates different tissues and organs.
Epithelial Tissues
- General functions include acting as barriers between the external environment and internal organs, secretions, and protections.
- Two major types:
- Simple Epithelia: Single layer of cells.
- Stratified Epithelia: Multiple layers of cells (2-20 or more).
- Shapes:
- Squamous: Flat, thin cells.
- Cuboidal: Cube-shaped cells.
- Columnar: Column-shaped cells.
- Locations in the body vary depending on type and function.
- Simple squamous epithelium is found in capillaries and air sacs of the lungs (alveoli).
- Cuboidal epithelium are in kidney tubules and glands.
- Columnar epithelium lines the digestive tract.
Connective Tissues
- General functions include supporting, connecting, and separating tissues/organs; protecting, binding organs, and immune protection, and movement/heat production.
- Components:
- Cells: Fibroblasts, macrophages.
- Fibers: Collagenous, reticular, elastic.
- Ground substance.
- Types of fibrous connective tissue:
- Tendons: Attach muscles to bones.
- Ligaments: Connect bones at joints.
- Blood: Liquid connective tissue.
- Blood composition:
- Plasma (55%): Liquid matrix, mainly water, electrolytes, nutrients, gases, hormones, and enzymes.
- Formed elements (45%): Red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
Muscle Tissues
- Skeletal muscle: Voluntary movements of the body, striated.
- Smooth muscle: Involuntary movements, found in walls of digestive tract, bladder, etc.; lacks striations.
- Cardiac muscle: Limited to the heart, striated cardiomyocytes.
Nervous Tissues
- Specialized for communication via electrical and chemical signals.
- Found in the brain and spinal cord.
- Composed of neurons (nerve cells) with dendrites, axons, and axon terminals, for transmitting signals.
