endocrine function

Question 1

the nervous and endocrine systems work together in different ways to do what in the body

Answer 1

coordinate all activities in the body

Question 2

explain the comparison of cells the nervous and endocrine system communicate with

Answer 2

The nervous system sends impulses to specific sets of cells (so its precise)

The endocrine system sends messages to virtually all cells in the body (so not as specific)

Question 3

compare the functions of nervous and endocrine system in the body

Answer 3

It stimulates muscle contraction and gland secretion

It changes the metabolic activities in the body

Question 4

compare the speed in which nervous and endocrine systems work at

Answer 4

Neurons work in milliseconds (fast)

Hormones may take up to several hours to exert their effects. (slow)

Question 5

what are the 8 broad areas that actions and effects of hormones can be categorized into

Answer 5

regulate the chemical composition and volume of extracellular fluid.

help to regulate metabolism and energy balance (building sugars into starch etc).

help to regulate the biological clock. (such as for growth in early ages)

help to regulate the contraction of smooth and cardiac muscle fibers and secretion by glands.

regulate certain activities of the immune system. (as immune system needs fats response to react)

control growth and development. (preventing diseases such as cancers etc)

contribute to the basic processes of reproduction, including gamete production, fertilisation, nourishment of the embryo and foetus and delivery.

help establish circadian rhythms (looks at 24 hour period, such as wakeness and sleep)

Question 6

name the 2 glad types

Answer 6

endocrine
exocrine

Question 7

explain endocrine glands

Answer 7

secrete hormones into interstitial fluid (never reach outside of the body)  blood circulation

Question 8

explain exocrine glands

Answer 8

– produce secretions which enter ducts  lumen (e.g. pancreatic digestive enzymes into small intestine) or outside the body (e.g. sweat glands/sebaceous glands)

Question 9

where are endocrine glads (hormone secretion only)
found

Answer 9

Pituitary (part of brain), thyroid, parathyroid (both in the neck), adrenal (produce adrenaline) & pineal (produces melatonin for patterns of sleep)

Question 10

where are the endocrine glands (hormone secretion + other functions) found

Answer 10

Hypothalamus (part of brain), thymus, pancreas, ovaries, testes, kidneys, stomach, liver, small intestine, skin, heart, adipose tissue & placenta

(all can produce hormones a swell a stheir other main functions already known)

Question 11

describe the limbic system

Answer 11

supports a variety of functions including emotion, behaviour, motivation, long-term memory, and olfaction. Emotional life is largely housed in the limbic system, and it has a great deal to do with the formation of memories.
