Types Of Tissues Flashcards
(9 cards)
What is connective tissue?
Connective tissue provides structure, support, defense, transport, and binding.
Components include cells, fibers (collagen and elastic), and ground substance (matrix).
What are the types of connective tissue?
Types of connective tissue include:
1. Loose connective tissue: Found around blood vessels/organs.
2. Fibrous connective tissue: Found in tendons and ligaments.
3. Cartilage: Found in joints, nose, ears.
4. Adipose tissue (fat): Stores energy and insulates.
5. Blood: Transports materials.
6. Bone: Provides structure.
What is epithelial tissue?
Epithelial tissue covers surfaces and lines cavities; it provides protection, secretion, absorption, exchange, and sensation.
Types are based on shape and layers.
What are the shapes of epithelial tissue?
Shapes of epithelial tissue include:
1. Squamous: Flat cells (e.g., in lungs and vessels).
2. Cuboidal: Cube-shaped (e.g., in glands).
3. Columnar: Tall, column-like (e.g., digestive tract).
What are the layers of epithelial tissue?
Layers of epithelial tissue include:
1. Simple: One layer.
2. Stratified: Multiple layers.
What is nervous tissue?
Nervous tissue is located in the brain, spinal cord, and peripheral nerves. Its main cell, the neuron, transmits electrical signals.
Parts include cell body, dendrites, and axon.
What are the parts of a neuron?
Parts of a neuron include:
1. Cell body: Contains nucleus and organelles.
2. Dendrites: Receive signals.
3. Axon: Sends signals; ends in terminals that communicate with other cells.
What is muscle tissue?
Muscle tissue produces movement, maintains posture, and generates heat.
It can contract and relax.
What are the types of muscle tissue?
Types of muscle tissue include:
1. Skeletal: Voluntary, striated, attached to bones by tendons.
2. Cardiac: Involuntary, striated, found in the heart.
3. Smooth: Involuntary, non-striated, found in organs and vessels.
