Q

What are the cell three basic parts?

A

Cell membrane (plasma membrane) - forms the cell’s outer surface

19
Q

The term Cardiomyocyte?

A

20
Q

What is the advantage for a cell having many microvilli (surface foldings)?

A

increases surface area without increasing cell size

Important for absorption and secretion

21
Q

important property of the cells which make up this tissue?

A

Contractility

Produces movement

22
Q

Nerve cells have long projections called?

A

Axons

23
Q

Why are these projections from some of the cells so long?

A

They are travelling long distances

24
Q

Longest axons in the body are found?

A

In the sciatic nerve

25
Q

(PQ) Up to 1 metre long or more?

A

Depends on how tall an individual is

26
Q

Fewer red blood cells would indicate?

A

anaemia
an=without
aemia=blood

27
Q

Had more white blood cells would indicate?

A

infection or leukaemia

leukos (greek) = white

28
Q

Describe the cell layer lining wall of the vessel?

A
