Biopsychology

Question 1

What are the 2 functions of the nervous system

Answer 1

•To collect,process and respond to information in the environment
•To coordinate the working of different organs and cells in the body

Question 2

What is the CNS made up of?

Answer 2

Spinal cord and brain

Question 3

What is the function of the Peripheral Nervous System

Answer 3

To transmit messages via millions of neurons (nerve cells), to and from the central nervous system

Question 4

What is the The Peripheral Nervous System divided into?

Answer 4

• Autonomic nervous system
• Somatic nervous system

Question 5

What is the function of The Autonomic Nervous System?

Answer 5

To govern vital functions in the body such as breathing, heart rate, digestion, sexual arousal and stress responses – involuntary effect

Question 6

What is the Autonomic Nervous System subdivided into?

Answer 6

• The sympathetic nervous system – it activates internal organs and
increases bodily activities
• The parasympathetic nervous system - it relaxes internal organs and decreases bodily activities

Question 7

What is the function of The Somatic Nervous System?

Answer 7

• This transmits information from receptor cells in the sense organs to the central nervous system.
• It receives information from the central nervous system that directs muscles to act – voluntary effect.

Question 8

What is the The Endocrine System?

Answer 8

The endocrine system works alongside the nervous system to control vital functions

Question 9

What does the The Pituitary Gland do?

Answer 9

it controls the release of hormones from all of the other endocrine glands in the body.

Question 10

What is the fight or flight response?

Answer 10

• This response is the way an animal responds when stressed. The body becomes physiologically aroused in readiness to fight an aggressor, or in some cases, flee.it is reflexive

Question 11

What is Adrenaline?

Answer 11

This is a hormone that is produced by the adrenal glands which is part of the body’s stress response system

Question 12

What is a Neuron?

Answer 12

The basic building blocks of the nervous system, neurons are nerve cells that process and transmit messages through electrical and chemical signals.

Question 13

What does the Sensory Neuron do?

Answer 13

Carry nerve impulses from sensory receptors to the spinal cord and brain = from the PNS to the CNS

Question 14

What does the Relay Neuron do?

Answer 14

Allow sensory and motor neurons to communicate with each other
They are the most common type of the neuron in the CNS

Question 15

What does the motor neuron do?

Answer 15

Carry nerve impulses from the spinal cord and brain to the effectors (muscles and glands) = from the CNS to the PNS

Question 16

What are Neurotransmitters?

Answer 16

Brain chemicals released from synaptic vesicles that relay signals across the synapse from one neuron to another. Neurotransm itters can be broadly divided into those that perform an inhibitory or an excitatory function

Question 17

What is FMRI?

Answer 17

works by detecting changes in blood oxygenation and blood flow that indicate increased neural activity.

Question 18

What is EEG?

Answer 18

records changes in electrical activity using electrodes attached to the scalp.

Question 19

What is ERP?

Answer 19

It records changes in electrical activity using electrodes attached to the scalp but uses a specific stimulus (sensory, cognitive or motor) to see where the activity is.

Question 20

What is Post Mortem?

Answer 20

They examine abnormalities in the structure of the brain which try to explain psychological abnormalities that people have before death.
