Biopsychology

Question 1

What is a Nueron?

Answer 1

The fundamental units of the brain and nervous system, the cells responsible for receiving sensory input from the external world,

Question 2

What do the dendrites do?

Answer 2

Receive signals from other celss

Question 3

what does the Axon Hillock do?

Answer 3

Generates impulse in the Neuron

Question 4

What does the Axon do?

Answer 4

Transfers Signals to other cells and organs

Question 5

What does the Myelin Sheath do?

Answer 5

Increase speed of signal

Question 6

What is the SYnapse

Answer 6

synapse is the space between the terminal button of one neuron and the dendrite of another neuro

Question 7

What is action potential

Answer 7

During the action potential, the electrical charge across the membrane changes
dramatically.

Question 8

What is reputake

Answer 8

Once an action potential has occurred, excess neurotransmitters in the synapse
either drift away, are broken down or are reabsorbed.

Question 9

What is a Neurotransmitter?

Answer 9

chemical messenger of the nervous system.

Question 10

The Peripheral nervous system is made up of two different parts:

Answer 10

Somatic nervous system -. Autonomic nervous system -

Question 11

. Autonomic nervous system -

Answer 11

• controls our internal organs and glands and can be
  divided into the Sympathetic and Parasympathetic nervous systems.

Question 12

Somatic nervous system

Answer 12

relays sensory and motor information to and from the
CNS.

Question 13

THE ENDOCRINE SYSTEM

Answer 13

A series of glands that produce hormones to regulate normal body functions.

Question 14

The cerebral cortex –

Answer 14

higher
level processes

Question 15

Thalamus

Answer 15

• sensory relay

Question 16

Hypothalamus

Answer 16

• homeostasis

Question 17

Pituitary gland

Answer 17

master
gland of the endocrine
system

Question 18

• Limbic system –

Answer 18

emotion and
memory circuit

Question 19

THE FRONTAL LOBE

Answer 19

Involved in executive functioning (planning, organization, judgement, attention,
reasoning), motor control, emotion, and language.

Question 20

Broca’s area -

Answer 20

in frontal lobe, region in the left hemisphere that is essential for language production.

Question 21

THE PARIETAL LOBE

Answer 21

Involved in processing various
sensory and perceptual
information.

Question 22

THE TEMPORAL LOBE

Answer 22

Associated with hearing, memory, emotion and some aspects of language.
Located on the side of the head (near the temples

Question 23

Wernicke’s area -

Answer 23

important for speech
comprehension.

Question 24

THE OCCIPITAL LOBE

Answer 24

Associated with visual processing.

Question 25

THE THALAMUS

Answer 25

The thalamus serves as the relay center of the brain where most senses (excluding smell) are routed before being directed to other areas of the brain for processing.

Question 26

THE LIMBIC SYSTEM

Answer 26

The Limbic system is involved in mediating emotional response and memory.

Question 27

Amygdala -

Answer 27

involved in our experience of emotion and tying emotional meaning to our memories. Involved in processing fear.

Question 28

Hippocampus

Answer 28

structure associated with learning and memory (in particular spatial memory).

Question 29

Hypothalamus

Answer 29

– regulates homeostatic processes including body temperature, appetite and blood pressure

Question 30

THE MIDBRAIN

Answer 30

Reticular formation - important in regulating the sleep/wake cycle, arousal, alertness, and motor activity.

Question 31

THE HINDBRAIN

Answer 31

Medulla - controls automated processes like breathing, blood pressure, and heart rate. Pons - connects the brain and the spinal cord; involved in regulating brain activity during sleep. Cerebellum - controls our balance, coordination, movement, and motor skills, and it is thought to be important in processing some types of memory

Question 32

ELECTROENCEPHALOGRAPHY

Answer 32

Involves recording the electrical activity of the brain via electrodes on the scalp.

Question 33

COMPUTERIZED TOMOGRAPHY (CT) SCAN

Answer 33

Involves x-rays and creates an image through x-rays passing through varied densities within the brain.

Question 34

POSITRON EMISSION TOMOGRAPHY (PET) SCAN

Answer 34

A PET scan is helpful for showing activity in different parts of the brain

Question 35

MRI AND FMRI

Answer 35

Magnetic resonance imaging (MRI) - magnetic fields used to produce a picture of the tissue being imaged.Functional magnetic resonance imaging (fMRI) - MRI that show changes in metabolic activity over time.
