Parts Of The Brain And Function

Front 1

What are the different areas of the brain?

Back 1

Cerebrum, Diencephalon, Cerebellum, Brainstem

Front 2

What are the different lobes of the cerebrum?

Back 2

Frontal, Temporal, Parietal, Occipital

Front 3

What is the function of the frontal lobe of the cerebrum?

Back 3

Contains Primary Motor Area that allows us to consciously move our skeletal muscles

Front 4

What is the function of the Temporal lobe of the cerebrum?

Back 4

Has the auditory area responsible for hearing and the olfacotry are responsible for smell

Front 5

What is the function of the Parietal lobe of the cerebrum?

Back 5

It contains the somatic sensory area which allows us to recognize heat, cold, pain, and pressure

Front 6

What is the function of the Occipital lobe of the cerebrum?

Back 6

It contains the the visual area responsible for sight

Front 7

What are the different parts of the diencephalon?

Back 7

Thalamus, Hypothalamus, Epithalamus

Front 8

What is the function of the Thalamus of the diencephalon?

Back 8

It is the relay station for sensory impulses passing upward to the sensory cortex

Front 9

What is the function of the Hypothalamus of the diencephalon?

Back 9

It plays a role in regulation of body temperature, water balance, and metabolism; an important part of the autonomic nervous system

Also part of the limbic system "emotional visceral brain"- thirst , appetite, sex, pain, and pleasure

Contains mamillary bodies which are reflex centers involved in olfaction

Front 10

What is the function of the Epithalamus of the diencephalon?

Back 10

Contains pineal body and choroid plexuses

Front 11

What is the function of the Cerebellum?

Back 11

Provides precise timing skeletal muscle activitiy and controls our balance

Front 12

What are the different parts of the Brainstem?

Back 12

midbrain, pons, medulla oblongata

Front 13

What is the function of the midbrain of the Brainstem?

Back 13

Has two bulging fiber tracts, called cerebral peduncles which convery ascending and descending impulses.

In the back of it (dorsally) are four rounded protusions call corpora quadrigemina which are reflex centers for vision and hearing

Front 14

What is the function of the pons of the Brainstem?

Back 14

Mostly made of fiber tracts

Front 15

What is the function of the medulla oblongata of the Brainstem?

Back 15

Important fiber tract area; has many nuclei that regulate visceral activities It contains centers that control heart rate, blood pressure, breathing, swallowing, and vomiting

Front 16

What is the reticular formation?

Back 16

A mass of gray matter that extends the whole length of the brain stem. Neurons of reticular formation responsible for motor control of the visceral organs

RAS (Reticular activating system) plays a role in consciousness and the awake/sleep cycles.

Front 17

What are the three layers of connective tissue that cover the brain?

Back 17

Dura Mater (Inner Most), Arachnoid Mater (Middle) and the Pia Mater (Outter Most)

Front 18

What do you call the two folds which the dura mater attaches to the cranial cavity?

Back 18

Flax Cerebi, Tentorium cerebelli (separates cerbellum from cerebrum)

Front 19

What is type of fluid is the subarachnoid space filled with?

Back 19

(CSF) Cerebrospinal fluid

Front 20

What bundle of capillaries form CSF?

Back 20

choroid plexuses

Front 21

What barrier is made up of the lest permeable capillaries in the body that keeps neurons separated form bloodborne substances?

Back 21

blood brain barrier

Front 22

What substances CAN get through the blood brain barrier?

Back 22

Water, glucose, and essential amino acids (good)

fats, respiratory gases, other fat-soulble molecules (bad)

Front 23

What substances CAN NOT get through the blood brain barrier?

Back 23

Metabolic wastes such as urea, toxins, proteins and most drugs
