Anatomy Of The Brain

Question 1

Cerebral Cortex

Answer 1

Outer part of the brain

Question 2

Gyrus

Answer 2

Bumps on the surface of the brain

Question 3

Sulcus

Answer 3

Sunken part (surcos) in the brain

Question 4

Where are the four lobes located?

Answer 4

Frontal Lobe: front
Parietal Lobe: middle
Temporal Lobe: side
Occipital Lobe: back

Question 5

Functions of Frontal Lobe

Answer 5

Reasoning, motor skills, higher-level cognition, and expressive language

Question 6

Motor cortex

Answer 6

Located in the frontal lobe, it carries out movements

Question 7

Functions of Parietal Lobe

Answer 7

Processing tactile sensory information like touch and pain

Question 8

Somatosensory cortex

Answer 8

Located in the parietal lobe, it involves the senses

Question 9

Functions of Temporal Lobe

Answer 9

Processing sounds and language, and encoding memory

Question 10

Primary auditory cortex

Answer 10

Located in the temporal lobe, process sounds and language

Question 11

Hippocampus

Answer 11

Located in the temporal lobe, in charge of learning and memory

Question 12

Functions of the Occipital Lobe

Answer 12

Interpreting visual stimuli and information

Question 13

Primary visual cortex

Answer 13

Receives and interprets information from the retinas

Question 14

Structure of the Brainstem

Answer 14

The brainstem is the most inferior portion of the brain,. It is composed of the medulla oblongata (lower part), midbrain (top part), and pons.

Question 15

Midbrain

Answer 15

Located in the brainstem and mesencephalon, it is associated with visual and auditory systems and information, eye movement, and body movement (red nucleus and substantia nigra).

Question 16

Medulla Oblongata

Answer 16

Located in the brainstem and myelencephalon, it is in charge of the vital autonomic functions like the cardiac, respiratory, and vomiting centers regulating heart rate, breathing, and blood pressure.

Question 17

Pons

Answer 17

Located in the brainstem and part of the mesencephalon, it carries signals connecting the cerebral cortex, the medulla, and the cerebellum.

Question 18

Cerebellum

Answer 18

Receives information from the balance system of the inner ear, sensory nerves, and auditory and visual systems. It’s also involved in the coordination of movements, motor learning, and cognitive functions.

Question 19

Thalamus

Answer 19

Processes and transmits movement and sensory information

Question 20

Hypothalamus

Answer 20

It controls hunger, thirst, emotions, body temperature, circadian rhythms, and the pituitary gland.

Question 21

The Limbic System

Answer 21

It’s in charge of emotional and behavioral responses

Question 22

Structure of the Limbic System

Answer 22

Amygdala, Hippocampus, Septal Area, and regions of the limbic cortex.

Question 23

Basal Ganglia

Answer 23

It’s large nuclei that partially surround the thalamus and control movement.
