Cardiac Muscle Tissue

Smooth Muscle Tissue

Skeletal Muscle Tissue

Nervous Tissue

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.
