Epithial And Connective Tissue Flashcards
What are the different types of tissue?
- Muscle
- Nervous
- Connective
- Epithelial
What is the function of connective tissue?
- Supports body parts and connects them together
What is the function of nervous tissue?
- Conducts nerve impulses by reacting to stimuli
What is the function of muscle tissue?
- Allows movement of body and individual structures
How is epithelial arranged?
- Simple
- Stratified
What is the function of a basement membrane?
- Providing oxygen and nutrients into the cell
Define ciliated epithelia and the function?
- Cilia on skin
- Aids moving dust and mucus
Where is simple squamous located?
- Alveoli
What is the function of simple squamous?
- Allows substances to diffuse across
Where is simple cuboidal located?
- Kidney tubules
What is the function of simple cuboidal?
- Allows diffusion of molecules
Where is psudostratified columnar located?
- Trachea
What is the function of psudostratified columnar?
- Allows molecules to be swept towards the throat due to mucus secretion
Where is simple columnar located?
- Small intestine
What is the function of simple columnar?
- Allows for nutrient a absorption and secretion of mucus
What are the different types of connective tissue?
- Loose connective tissue
- Dense connective tissue
- Specialised connective tissue
What are the names of the different epithelial tissues?
- Ciliated epithelial tissue
- Cuboidal
- Squamous
What are the functions of ciliated epithelial tissue?
- Removes dirt and foreign bodies to prevent infection
- Moves mucous secretions for effective gaseous exchange
How would lack of calcium affect muscle contraction?
- There would be less muscle contraction because there would be fewer myosin binding sites exposed if there was not sufficient calcium available
Compare fast and slow twitch muscle fibres
Slow twitch
•provide power
•store more oxygen for aerobic respiration
•shorter recovery rate
Fast twitch
• Enables muscles to move quickly
• short bursts of energy
• anaerobic respiration
• builds up lactic acid
What is the function of simple squamous?
- Allows substances to diffuse across
Where is simple squamous located?
- Alveoli
What is the function of simple cuboidal?
- Allows the diffusion and secretion of molecules
Where is simple cuboidal located?
- Lining kidney tubules
What is the function of simple columnar
- Nutrient absorption and secretion of substances such as mucus
Where is simple columnar located?
- Lines the small intestine
What is the function of pseudostratified
- Allow impurities to be swept towards the throat due to the secretion of mucus
Where is psudostratified located?
Trachea
What are examples of loose connective tissue?
- Adipose-under skin, around heart,kidneys and mammary glands - stores fat and provides insulation
- Areolar-under all epithelial tissue-protects organs,blood vessels and nerves- gives strength to epithelial tissue
What are examples of dense connective tissue?
- Fibrous- located in ligaments- attaches bones to bones and provides support to joints.
- Elastic fibres - located in tendons- attaches muscles to bones.
What are examples of specialised connective tissue?
- Bone-location:skeleton- forms the skeleton; protects and supports the main organs of the body-anchors the muscles
- Cartilage- located in intervertebral discs, between ribs and sternum, external ear- smooths surfaces at joints and prevents collapse of trachea and bronchi
- Blood- circulates in the cardiovascular system-transports substances around the body
