|
Where is skeletal muscle tissue located? |
Muscles attached to bones |
|
|
What are the structural characteristics of skeletal muscle? |
Striated tissue (alternating light/dark bands) |
|
|
What are the functional characteristics of skeletal muscle? |
They cause voluntary movement |
|
|
Where is smooth muscle tissue located? |
Walls of internal organs |
|
|
What are the structural characteristics of smooth muscle? |
Spindle shaped cells, one nucleus located near center of cell lacks striations. |
|
|
What are the functional characteristics of smooth muscle? |
Involuntary muscle movement. |
|
|
Where is cardiac muscle tissue located? |
Heart |
|
|
What are the structural characteristics of cardiac muscle? |
Striated, cells joined end-to-end with intercalated discs, self exciting |
|
|
What are the functional characteristics of cardiac muscle? |
Involuntary heart movement |
|
|
Where is nervous tissue located? |
Brain, spinal cord, pheripheral nerves |
|
|
What is the function of nervous tissue? |
Sensory reception, conduction of nerve impulses |
|
|
Describe the function of the two major cell types in nervous tissue. |
Neurons conduct nerve impluse, limit ability to repair/divide Neuroglial cells provide framework for neural tissue, regulate fluids, bring nutrients to neurons. |
|
|
Where are serous membranes found?
|
Lines cavities that lack openings to the outside |
|
|
What is the function of serous membranes? |
secretes serous fluid for protection |
|
|
Where are mucous membranes found? |
Line cavities and tubes with openings to the outside. |
|
|
How are mucous membranes different from serous membranes? |
Mucous membranes have openings to the outside and secretes mucus from goblet cells. |
|
|
What type of specialized cells can be found in mucous membranes? What is their function? |
Goblet cells; Secrete mucous |
|
|
What is the cutaneous membrane? |
Skin |
|
|
Where are synovial membranes located? |
Line joints at end of bones |
|
|
What is the function of synovial membranes? |
Secretes synovial fluid which lubricates joints. |
|
|
Describe how aging affects tissues. |
repair and maintenance grow less efficent, hormonal and lifestyle changes affect the structure and chemical compositions of tissues, epithelial tissues get thinner, connective tissue gets more fragile, equals more bruises joint pain broken bones, cardiac muscle and neurons cannot be replaced, accumulative loss from minor damage can lead to major health problems such as cardiovascular disease and deterioration in a mental function. |
