Biopsychology

The Central Nervous System (CNS)
The CNS is made up of your spinal cord and brain. It receives information from the senses and controls the body's response.
1 of 19
The Spinal Cord
The main function of the spinal cord is to relay information to your brain and the rest of your body. This allows the brain to monitor and regulate bodily processes E.g digestion, breathing and to coordinate voluntary movements.
2 of 19
The Brain
The part of the CNS that is responsible for coordinating sensation, intellectual and nervous activity.
3 of 19
Cerebrum
This is the largest part of the brain, and is further divided into four different lobes.
4 of 19
Frontal Lobe
The frontal lobes are involved with functions such a speech, thought and learning.
5 of 19
Parietal Lobe
The Parietal Lobes process sensory information such as touch, temperature and pain.
6 of 19
Occipital Lobe
The Occipital Lobes process visual information.
7 of 19
Temporal Lobe
The Temporal Lobes are involved with hearing and memory.
8 of 19
Broca's Area
An area of the frontal lobe of the brain, usually in the left hemisphere, related to speech production. (Just above the tip of the ear)
9 of 19
Wernicke's Area
An area in the temporal lobe of the brain important in the comprehension of language. (Just in front of your ear)
10 of 19
Somatosensory Cortex
A region of the brain that processes input from sensory receptors in the body that are sensitive to touch.
11 of 19
Motor Cortex
A region of the brain responsible for the generation of voluntary motor movements.
12 of 19
Auditory Cortex
The Auditory Centre in the brain is concerned with hearing.
13 of 19
Visual Cortex
The visual cortex spans across both hemispheres, with the right hemisphere receiving its input from the left-hand side of the visual field, while the visual cortex in the left hemisphere receives input from the right-hand side of the visual field.
14 of 19
The Peripheral Nervous System (PNS)
The part of the nervous system that is outside of the brain and spinal cord. The purpose of this is to relay nerve impulses from the CNS to the rest of the body and from the body back to the CNS.
15 of 19
The Somatic Nervous System
The part of the peripheral nervous system responsible for carrying sensory and motor information to and from the central nervous system.
16 of 19
The Autonomic Nervous System (ANS)
This governs the brains involuntary activities (E.g stress, heartbeat) and is self-regulating (i.e autonomous). It is divided into the sympathetic branch (fight or flight) and the parasympathetic branch (rest and digest).
17 of 19
The Sympathetic Nervous System
This is our fight or flight response. Neurons from the SNS travel to virtually every organ and gland within the body, preparing the body for the rapid action necessary when the individual is under threat.
18 of 19
The Sympathetic Nervous System (Continued...)
For example, the SNS causes an increase in our heart rate which allows for greater blood flow to skeletal muscles or the Adrenal medulla is stimulated to release adrenaline.
