Q

What do the dendrites do in the neuron?

A

highly branched processes that provide a large surface area for the reception of signals from other neurons

21
Q

What does the axon do in the neuron?

A

a long extension the usually conducts impulses away from the cell body

22
Q

What is a neuroglia?

A

support, insulate, and protect neurons

23
Q

neuroglia is also known as _____ cells

24
Q

neuroglia (or glial cells) communicate with other _____ cells and with _______

A

glial

neurons

25
Q

True or False: neuroglia (or glial cells) decrease the rate at which impulses are conducted by neurons

A

False; neuroglia (or glial cells) increase the rate at which impulses are conducted by neurons

26
Q

_________ (or ____ ____) provide neurons with nutrients from nearby blood vessels

A

neuroglia (glial cells)

27
Q

What are the different types of cell junctions?

A

1) Tight Junctions
2) Adhesion Junctions
3) Gap Junctions

28
Q

Which type of junction is this: creates an impermeable junction that prevents the exchange of materials between cells

A

Tight Junctions

29
Q

Which type of junction is this: found between epithelial cells of the digestive tract, where they prevent digestive enzymes and microorganisms from entering the blood

A

Tight Junctions

30
Q

Which type of junction is this: holds cells together despite stretching

A

Adhesion Junctions

31
Q

Which type of junction is this: found in tissues that are often stretched, such as the skin and the openings of the uterus

A

Adhesion Junctions

32
Q

Which type of junction is this: allows cells to communicate by allowing small molecules and ions to pass from cell to cell

A

Gap Junctions

33
Q

Which type of junction is this: found in epithelia in which the movement of ions coordinates functions, such as the beating of cilia; found in excitable tissue such as heart and smooth muscle

A

Gap Junctions

34
Q

What is an organ?

A

a structure composed of 2 or more different tissues that work together to perform a specific function

35
Q

What is an organ system?

A

a group of organs with a common function

36
Q

What are the 2 important functions of cavities?

A

1) they help protect the vital organs from being damaged when we walk or jump
2) they allow organs to slide past one another and change shape

37
Q

What are the two main body cavities?

A

1) Ventral (towards the abdomen)

2) Dorsal (towards the back)

38
Q

What are the two types of cavities within the ventral cavity?

A

1) thoracic (chest) cavity

2) abdominal cavity

39
Q

What are the two types of cavities within the thoracic (chest) cavity?

A
