Animal 3

Question 1

how does information get from one place to another

Answer 1

electrical and chemical signals

Question 2

chemical signalling; through the blood, traveling throughout the body; affects target cells to alter physiology and behavior

Answer 2

hormones

Question 3

how does the endocrine hormones achieve specificity?

Answer 3

ligand receptor mechanisms, only the right cells with specific receptor can be target cell and responds to that hormone

Question 4

how does the nervous system achieve specificity through electrical signals?

Answer 4

proximity of neurons and target cells

Question 5

NS systems is specialized for _________ responses to environment while the endocrine system is specialized for coordinating ______ changes that affect the entire bod

Answer 5

immediate and rapid

gradual

Question 6

cells that support and maintain homeostasis
form myelin
‘nourish/support neurons in CNS and PNS

Answer 6

glial cells

Question 7

all neurons extending out of brain and spinal cord bringing into to, away is part of the _________

Answer 7

peripheral NS

Question 8

bundles of axons

Answer 8

nerves

Question 9

cluster pf cell bodies bundled together outside of the CNS

Answer 9

ganglia/ ganglion

Question 10

____ output: any kind of response initiated by neurons coming out of CNS

Answer 10

motor output

Question 11

inter neurons are found solely in the _______

Answer 11

Central nervous system

Question 12

what is the pathway of a message for a reflex reaction

Answer 12

sensory neuron – motor neuron

Question 13

what two things regulate the endocrine system

Answer 13

hypothalamus and the pituitary gland

Question 14

posterior pituitary is an extension of ______ in the hypothalamus

Answer 14

nervous tissue axons of neurosecretory cells

Question 15

anterior pituitary is formed by ____ tissue

Answer 15

endocrine

Question 16

neurons that secrete hormones directly into the bloodstream

Answer 16

neurosecretory cells

Question 17

network of blood vessels is called a:

- its importance

Answer 17

portal vessel

allows direct route to pituitary (otherwise would have the go through the blood stream which take longer)

Question 18

organisation of endocrine glans, hypothalamus and the postier and anterior pituitary

Answer 18

hypothalamus–. pituitary–. other endocrine glands

Question 19

the hypothalamus connects ____ and ____ systems

Answer 19

nervous and endocrine systems

Question 20

water soluble hormones are contained in a vesicle true or false

Answer 20

true

Question 21

lipid soluble hormones are contain in a vesicle true or false
why
what happens

Answer 21

false, cannot be contained in a biological membrane, would just seep out

• made as needed
• typically involved in more ling-term function

Question 22

how do water soluble hormones get out of a vessicle

Answer 22

need membrane protein on outside to bind to receptor

Question 23

how do lipid soluble able to regulate gene expression if they are not brought to the location by a vessicle

Answer 23

they ,move through membranes are start interacting directly with the nucleus

Question 24

are the responses the same if:

• different cells
• same kind of receptors

Answer 24

different responses

Question 25

are the responses the same if:

• same cell type
• different receptor

Answer 25

different responses

Question 26

pairs of hormones whose actions oppose each other

examples

Answer 26

antagonistic hormones

ex: insulin and glucagon
