Question 5

Describe the pathway of a somatic nervous response

Answer 5

Sense organs- sensory neurones- CNS- motor nerve- muscles and glands

Question 6

What are the 2 branches of the autonomic nervous system

Answer 6

Sympathetic and parasympathetic

Question 7

Sympathetic and parasympathetic neurones are antagonistic in action what does this mean

Answer 7

Antagonistic in action means they act in opposite ways

Answer 14

Increases rate of persistalsis

Question 15

Describe the effect of the parasympathetic system on intestinal secretions

Answer 15

Increases production of intestinal secretions

Question 16

Impulses from several neurons travel to one neuron. This increases the sensitivity to excitatory or inhibitory signals, which type of pathway is this

Answer 16

Converging neural pathway

Question 17

Impulses from one neuron to several neurons so affecting more than one destination at the same time. Which type of neural pathway is this

Answer 17

Diverging neural pathway

Question 18

Neurons layer in the pathway link with earlier neurons, sending the impulses back through the pathway. This allows repeated stimulation of the pathway, which type of neural pathway is this 

Answer 18

Reverberating pathway

Question 19

Describe the function of the cerebral cortex 

Answer 19

The centre of conscious thought, it also recalls memories and alters behaviour in the light of experience 

Question 20

What areas does the cerebral cortex contain? 

Answer 20

Sensory areas motor areas and association areas 

Question 21

What are association areas involved in? 

Answer 21

Language processing, personality, imagination, and intelligence 

Question 22

Where does the left city hemisphere get its information from and what does it control? 

Answer 22

It gets its information from the left visual field, and it controls the left side of the body 

Question 23

How is there transfer of information between the cerebral hemispheres?

Answer 23

 Through the corpus callosum
