Q

If hormones reach every cell in the body, why do some cells respond to specific hormones?

A

Because of receptor ( they reach the target tissues or target cells that have specific receptor that bind to that hormone )

Q

The type of signals that may travel long distance to reach target cells is………

A

both chemical and electrical signals

17
Q

What the main function of junctions in electrical signals transmission?

A

Junctions are working as a connection between a neurones to allows to that signals passing between a neurones to reach a target tissues as a result of signals effect

18
Q

The type of signals that reach the target tissues by travel distinct pathway along neurones by specialised junctions is………

A

electrical signals

19
Q

The type of signals that are fast and last for short time is………

A

electrical signals

20
Q

The type of signals that are gradual response and last longer is………

A

chemical signals (hormones)

21
Q

The type of signals that reach the target tissues by travel through the blood to all body is………

A

chemical signals (hormones)

22
Q

The adrenaline hormone from adrenal gland could be……
a)electrical signals

c)both of them

A

C) both of them

23
Q

The right order for the hormonal signal……

A

reception ➡️ signal transduction ➡️ response

24
Q

The type of chemical signal that pass directly through the cell membrane without a receptor is ………

A

lipid-soluble hormones

25
