Brain (Cerebullum to Limbic System)

Question 1

Part of the Brain, located below the occipital lobe of the cerebrum, and posterior to the Pons and Medulla

Answer 1

Cerebellum

Question 2

The strong, horizontal fold of dura mater that is attached along the midline to the Falx Cerebri and separates the cerebellum from the basal surface of the occipital and temporal lobes

Answer 2

Tentorium Cerebelli

Question 3

The scythe-shaped vertical fold of the duramater, in the longitudinal fissure, between the two cerebral hemispheres.

It is attached anteriorly to the front of the skull and caudally to the upper surface of the Tentorium Cerebelli

Answer 3

Falx Cerebri

Question 4

The cerebellum is important for?

Answer 4

Coordination of movements and maintenance of balance (Intentional movement)

Question 5

Part of the brain located just superior to the Spinal Cord

Answer 5

Brain Stem

Question 6

3 parts of the Brain Stem

Answer 6

1) Medulla (caudal)
2) Pons (intermediate)
3) Mid Brain (Superior)

Question 7

The Brain Stem is concerned with the vital (life sustaining) functions of?

Answer 7

The ANS

Question 8

The Brain Stem contains both motor and sensory tracts that connect? (2)

Answer 8

Spinal Cord and Various Regions of the Brain

Question 9

The Brain Stem is the site of most of the 12….?

Answer 9

Cranial Nerve Nuclei

Ex. CN XI, The accessory nerve –> Innervates Trapezius and SCM

Question 10

Part of the Brain Stem that “attaches” to the Spinal Cord

It contains nuclei that are reflex centers for regulation of various vital functions.

Answer 10

Medulla Oblongata

Question 11

Vital functions regulated by the Medulla Oblongata (7)

Answer 11

• Heart Rate
• Respiratory Rate
• Vasoconstriction
• Swallowing
• Coughing
• Vomiting (Emesis)
• Cardiovascular Control

Question 12

Part of the Brain Stem, superior to the Medulla

Answer 12

Pons

Question 13

Relays nerve impulses between the cortex and cerebellum

Answer 13

Pontine Nuclei

Question 14

The Pons, with the medulla, helps control?

Answer 14

Breathing

Question 15

Part of the brain stem that mediates auditory and visual (oculomotor) reflexes

Answer 15

Mid Brain

Question 16

An involuntary response to a stimulus

Answer 16

A reflex

Question 17

Part of the Brain closely associated with motor system pathways of the basal ganglia

Answer 17

Substantia Nigra

Question 18

Chemical produced in the Substantia Nigra that plays a role in motivation and movement in all animals

Answer 18

Dopamine

Question 19

A large part of the Brain Stem, consisting of small areas of loosely clustered nuclei and tracts.

It helps maintain consciousness, causes awakening from sleep, filters out unimportant information and contributes to regulating muscle tone

Answer 19

Reticular Formation

DO THE RETICULAR FORMATION (dance)

Question 20

Part of the Brain

Wraps around the Brain Stem and lies beneath the Cerebral Cortex.

It contains many parts and its structures are also connected with other major structures such as the Cortex and basal Ganglia

A network of centres that are also referred to as the ‘emotional brain’

Answer 20

The Limbic System

Question 21

Part of the Limbic system that plays an important role in emotional behaviours, especially fear

Answer 21

Amygdala

Question 22

The Brain’s pleasure center - plays a role in sexual arousal and the ‘high’ derived from certain recreational drugs.

These responses are heavily modulated by dopaminergic projections from the limbic system

Answer 22

Nucleus Accumbens

SEX, DRUGS AND ROCK’n’ROLL

Question 23

Part of the Limbic System

Involved the consolidation of ‘short term’ memory into long term memory and other complex cognitive processes

Answer 23

Hippocampus

Question 24

The limbic system is also tightly connected to?

Answer 24

the Prefrontal Cortex

Question 25

The anterior part of the frontal lobes of the brain, lying in the front of the motor and premotor cortices

Answer 25

the Prefrontal Cortex

Question 26

The Prefrontal cortex has been implicated in?

Answer 26

- Planning complex cognitive behaviour - Personality expression - Decision making - Moderation social behaviour

Question 27

The prefrontal cortex develops later in life and is often responsible for two traits in teenagers

Answer 27

- Risk Taking | - Poor Decision Making

Question 28

Situated below and in front of the thalamus, and above the pituitary gland An important part of the limbic system Involved in controlling the ANS and the endocrine system, and organizes behaviours Plays an important role in the integration of the endocrine and nervous systems

Answer 28

Hypothalamus

Question 29

An important sensory relay station between the rest of the body and the cerebrum

Answer 29

Thalamus

Question 30

Functions of the Hypothalamus

Answer 30

Control of hunger, thirst and body temperature

Question 31

Located in the Hypothalamus It controls your circadian rhythms via the pineal glands secretion of the hormone melatonin

Answer 31

Suprachiasmatic Nucleus

Question 32

This hormone targets the hypothalamus helps it to establish the body's circadian rhythm

Answer 32

Melatonin
