Tissue Classification Review Sheet Exercise 6: Review Sheet Exercise 6 Classification Of Tissues Answer Key
The purpose of this exercise is to review the different types of tissues in the body and their functions. The exercise covers epithelial, connective, muscle, and nervous tissues.
Epithelial Tissue, Review sheet exercise 6 classification of tissues answer key
| Type | Characteristics | Functions |
|---|---|---|
| Simple Squamous | Thin, flat cells | Diffusion, filtration, secretion |
| Simple Cuboidal | Cube-shaped cells | Secretion, absorption |
| Simple Columnar | Tall, column-shaped cells | Secretion, absorption, protection |
| Pseudostratified Columnar | Appears stratified but is actually not | Secretion, absorption, protection |
| Stratified Squamous | Multiple layers of flat cells | Protection |
| Stratified Cuboidal | Multiple layers of cube-shaped cells | Protection, secretion |
| Stratified Columnar | Multiple layers of column-shaped cells | Protection, secretion, absorption |
| Transitional | Cells that change shape depending on the state of the organ | Protection, stretching |
Flowchart for Epithelial Tissue Classification:
- Number of cell layers:Simple (one layer) or stratified (multiple layers)
- Cell shape:Squamous (flat), cuboidal (cube-shaped), or columnar (tall and narrow)
Connective Tissue
Connective tissue is the most abundant type of tissue in the body. It supports, connects, and protects other tissues and organs.
| Type | Composition | Functions |
|---|---|---|
| Loose Connective Tissue | Loosely arranged cells in a matrix of collagen and elastin | Support, cushioning |
| Dense Connective Tissue | Tightly packed cells in a matrix of collagen and elastin | Support, protection |
| Adipose Tissue | Cells filled with fat | Energy storage, insulation |
| Cartilage | Cells in a matrix of collagen and proteoglycans | Support, cushioning |
| Bone | Cells in a matrix of collagen and calcium phosphate | Support, protection, storage |
| Blood | Cells in a liquid matrix | Transport, protection, regulation |
Muscle Tissue
Muscle tissue is responsible for movement. There are three types of muscle tissue: skeletal, smooth, and cardiac.
| Type | Structure | Functions |
|---|---|---|
| Skeletal Muscle | Striated, voluntary | Movement of bones |
| Smooth Muscle | Non-striated, involuntary | Movement of organs and blood vessels |
| Cardiac Muscle | Striated, involuntary | Pumping of blood |
Nervous Tissue
Nervous tissue is responsible for communication and coordination. It is composed of neurons and glial cells.
Diagram of a Neuron:
- Cell body:Contains the nucleus and other organelles
- Dendrites:Receive signals from other neurons
- Axon:Transmits signals to other neurons
- Myelin sheath:Insulates the axon and speeds up signal transmission
- Synapse:The junction between two neurons where signals are transmitted
