Tissues (Lecture 1) Flashcards
What are the 4 types of tissues?
- Epithelial tissue
- Connective tissue
- Muscle Tissue
- Nervous Tissue
What are the functions of Epithelial tissue?
- Provide physical protection i.e. skin.
- Control Permeability. (Substance that enters or leaves the body must cross an epithelium).
- Provide sensation i.e. can detect changes in the environment and convey information about such changes to the nervous system.
- Produce specialised secretions
What are the two types of epithelial tissue?
- Epithelia (the covering tissue)
2. The glands tissue ( this can be split up into exocrine glands and endocrine glands. )
What are the three types of connective tissue?
- Connective tissue proper ( loose and dense)
- Fluid connective tissue (blood and Lymph)
- Supporting connective tissue. (cartilage and bone)
What are the functions of connective tissue?
- Connective tissue connects parts of the body. How we transport fluid and dissolved materials around the body
- Protects delicate organs
- Supports/interconnects other tissue
- Stores energy i.e. Triglycerides
- Defends the body from invading microorganisms.
What are the three types of muscle tissues?
- Cardiac muscle tissue which is from your heart
- Smooth muscle tissue from organs
- Skeletal muscle tissues is attached to your skeleton (allows movement).
What is the nervous tissue?
Nervous tissue is sending information around the body. If you have muscle attached to bone these muscles will not contract to move unless something tells it too. Nervous tissue also receives information i.e. feel, see etc.
What are the functions of the Neuroglia?
- Maintain physical structure and nervous tissue
- Repair nervous tissue framework after injury
- Perform phagocytosis
- Provide nutrients to neurons
- Regulate the composition of the interstitial fluid surrounding neurons.
What are the three types of loose connective proper tissue called?
Areolar tissue, adipose tissue, and reticular tissue.
Nervous tissues contain two types of cells?
- Neurons
2. Neuroglia
