Mid year exam assistance thread

Hi everyone,

Given that the psych exam is less than two weeks away I thought I would create a thread to deal with specific questions or issues that arise during your final days of study. I am sure that myself and Eriny will endeavour to respond to any questions you have as quickly as we can.

Good luck and don't hesitate to post your thoughts and questions  :)

ohh good idea

i got one:

from the TSSM 2007 exam:

Question 15
Neurons that pass information from the peripheral nervous system to the central nervous system are called:

A. Sensory neurons
B. Afferent neurons
C. Reflex neurons
D. Motor neurons

I chose answer B, however the answers to the exam said answer A was correct.  I thought sensory neurons and afferent neurons were one and the same? (i chose answer B though cos it was most correct  :-\)

Yeah it's a stupid question. Both A & B are correct, they're the same thing.

Sensory neurons=Afferent neurons
Motor neurons=Efferent neurons

Afferent/efferent neurons are probably regarded as outdated terminology, they prefer you to use the terms sensory and motor neurons.

There was a great mnemonic to do with that: SAME (sensory afferent, motor efferent).

It would be sensory as the PNS only sends sensory info to the CNS, as it cannont sent Motor info, however, it can only RECEIVE motor info from the CNS. (hope that makes sense.

Basically, sensory is going to the brain and motor is coming from the brain to a specific body part.Therefore A is the only correct response.

I was about to post that myself! It's a very, very useful acronym.

psychlaw,

No, you don't technically need to know about white and grey matter- they were part of the study design years ago.

And no, you don't need to know about the anatomy of a neuron (myelin sheath/axon).

No it's not assumed knowledge. You not required to even complete unit 1 or 2 before tackling unit 3/4.

If you know why it's grey (i.e. the presence of many call bodies), then that would be ample knowledge.
