Parts Of The Brain

Question 1

Corpus Callosum

Answer 1

The corpus callosum connects the left side of the brain to the right side, each side being known as a hemisphere.

Question 2

Cerebellum

Answer 2

“Little brain”

The cerebellum is important for making postural adjustments in order to maintain balance.

Question 3

Limbic system

Answer 3

“Emotional brain”

The part of the brain involved in our behavioural and emotional responses, especially when it comes to behaviours we need for survival: feeding, reproduction and caring for our young, and fight or flight responses.

Question 4

Brain Stem

Answer 4

The posterior stalk-like part of the brain that connects the cerebrum with the spinal cord. In the human brain the brainstem is composed of the midbrain, the pons, and the medulla oblongata.

Question 5

Thalamus

Answer 5

A small structure within the brain located just above the brain stem between the cerebral cortex and the midbrain and has extensive nerve connections to both. The primary function of the thalamus is to relay motor and sensory signals to the cerebral cortex.

Question 6

Hypothalamus

Answer 6

Plays a crucial role in many important functions, including: releasing hormones. regulating body temperature.

Question 7

Amygdala

Answer 7

Two almond-shaped neural clusters of nuclei located deep and medially within the temporal lobes of the brain’s cerebrum

Question 8

Hippocampus

Answer 8

A complex brain structure embedded deep into temporal lobe. It has a major role in learning and memory.

Question 9

Pons

Answer 9

While involved in the regulation of functions carried out by the cranial nerves it houses, works together with the medulla oblongata to serve an especially critical role in generating the respiratory rhythm of breathing. Active functioning of the pons may also be fundamental to rapid eye movement (REM) sleep.

Question 10

Medulla Oblongata

Answer 10

It plays an essential role in passing messages between your spinal cord and brain. It’s also essential for regulating your cardiovascular and respiratory systems. … Neuroanatomy, medulla oblongata.

Question 11

Primary Motor Cortex

Answer 11

Muscular Control, Coordination

The area that provides the most important signal for the production of skilled movements. Electrical stimulation of this area results in focal movements of muscle groups on the opposite side of the body, depending on the area stimulated.

Question 12

Primary Somatosensory Cortex

Answer 12

Sense of Touch

Is responsible for processing somatic sensations. These sensations arise from receptors positioned throughout the body that are responsible for detecting touch.

Question 13

Midbrain (mesencephalon)

Answer 13

Is the topmost part of the brainstem, the connection central between the brain and the spinal cord. … Of the 12 cranial nerves, two thread directly from the midbrain - the oculomotor and trochlear nerves, responsible for eye and eyelid movement.

Information relay to forebrain, wakefulness, drowsiness, involuntary movements

Question 14

Diencephalon

Answer 14

The caudal (posterior) part of the forebrain, containing the epithalamus, thalamus, hypothalamus, and ventral thalamus and the third ventricle.

Question 15

Forebrain

Answer 15

The forebrain controls body temperature, reproductive functions, eating, sleeping, and the display of emotions.

Question 16

Broca’s area

Answer 16

Is a region of the brain concerned with the production of speech, located in the cortex of the dominant frontal lobe. Damage in this area causes Broca’s aphasia, characterized by hesitant and fragmented speech with little grammatical structure.

Question 17

Three main parts of the hindbrain (rhombencephalon)

Answer 17

Pons, cerebellum, and medulla oblongata.

Most of the 12 cranial nerves are found in the hindbrain.
