Frage 1
Frage
What does the Nervous System enable humans to do?
Frage 2
Frage
Information from [blank_start]receptors[blank_end] passes along cells ([blank_start]neurones[blank_end]) as impulses to the central nervous system (the [blank_start]brain[blank_end] or [blank_start]spinal cord[blank_end]). The brain coordinates the [blank_start]response[blank_end].
Antworten
-
receptors
-
neurones

response
Frage 3
Frage
The cerebral cortex is concerned with consciousness, co-ordination and unconscious activities.
Frage 4
Frage
The cerebellum is concerned mainly with the coordination of muscular activity.
Frage 5
Frage
The medulla is concerned with unconscious activities such as heartbeat and breathing.
Frage 6
Frage
Scientists have been able to map regions of the brain to paticular fuctions by studying patients with brain damage, [blank_start]electrically stimulating[blank_end] different parts of the brain and using [blank_start]MRI[blank_end] scanning techniques.
Antworten
-
MRI
-
CAT
-
electrically stimulating
-
artificially stimulating
Frage 7
Frage
[blank_start]Reflex[blank_end] actions are [blank_start]automatic[blank_end] and rapid. They often involve [blank_start]sensory[blank_end], [blank_start]relay[blank_end] and [blank_start]motor[blank_end] neurones.

Frage 8
Frage
In a simple reflex action such as pain-withdrawal reflex: (step 1)
Frage 9
Frage
Reflex actions step 2:
Antworten
-
at a synapse between a sensory neurone and a relay neurone in the CNS, a chemical is released that causes an impulse to be sent along a relay neurone
-
at a synapse between a relay neurone and a motor neurone in the CNS, chemical energyl is released that causes an impulse to be sent along a motor neurone
Frage 10
Frage
Simple reflex action part 3:
Antworten
-
a chemical is then released at the synapse between a relay neurone an motor neurone in the central nervous system, causing impulses to be sent along a motor neurone to the effector
-
at a synapse between a sensory neurone and a relay neurone in the CNS, a chemical is released that causes an impulse to be sent along a relay neurone
Frage 11
Frage
Simple reflex action part 4:
Antworten
-
the effector is either a muscle or a gland: a muscle responds by contracting and a gland responds by secreting chemical substances
-
the effector is either a nerve or a gland: a nerve responds by sending impulses to the brain and a gland responds by secreting chemical substances
