Q

What is reputake

A

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

Q

. Autonomic nervous system -

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

Q

Hypothalamus

A
  • homeostasis
17
Q

Pituitary gland

A

master
gland of the endocrine
system

18
Q
  • Limbic system –
A

emotion and
memory circuit

19
Q

THE FRONTAL LOBE

A

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

20
Q

Broca’s area -

A

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

21
Q

THE PARIETAL LOBE

A

Involved in processing various
sensory and perceptual
information.

22
Q

THE TEMPORAL LOBE

A

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

23
Q

Wernicke’s area -

A

important for speech
comprehension.

24
Q

THE OCCIPITAL LOBE

A

Associated with visual processing.

25
Q

THE THALAMUS

A

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.

26
Q

THE LIMBIC SYSTEM

A

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

27
Q

Amygdala -

A

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

28
Q

Hippocampus

A

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

29
Q

Hypothalamus

A

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

30
Q

THE MIDBRAIN

A

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

31
Q

THE HINDBRAIN

A

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

32
Q

ELECTROENCEPHALOGRAPHY

A

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

33
Q

COMPUTERIZED TOMOGRAPHY (CT) SCAN

A

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

34
Q

POSITRON EMISSION TOMOGRAPHY (PET) SCAN

A

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

35
Q

MRI AND FMRI

A

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.
