Question 6

brain overview

Answer 6

three-pound organ that controls all functions of the body, interprets information from the outside world
Intelligence, creativity, emotion, and memory are governed by the brain.
Protected within the skull, the brain is composed of the cerebrum, cerebellum, and brainstem.

Question 7

CNS and PNS

Answer 7

The central nervous system (CNS) is composed of the brain and spinal cord. The peripheral nervous system (PNS) is composed of spinal nerves that branch from the spinal cord and cranial nerves that branch from the brain

Question 8

Cerebrum

Answer 8

Is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.

Question 9

Cerebellum

Answer 9

Is located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance.

Question 10

Brainstem

Answer 10

acts as a relay centre connecting the cerebrum and cerebellum to the spinal cord. It performs many automatic functions such as breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing.

Question 11

hemispheres of the brain

Answer 11

The cerebrum is divided into two halves: the right and left hemispheres
They are joined by a bundle of fibers called the corpus callosum that transmits messages from one side to the other.
Each hemisphere controls the opposite side of the body. If a stroke occurs on the right side of the brain, your left arm or leg may be weak or paralyzed.
left hemisphere controls speech, comprehension, arithmetic, and writing. left is dominant.
Right hemisphere controls creativity, spatial ability, artistic, and musical skills.

Question 12

Frontal lobe

Answer 12

Personality, behaviour, emotions
Judgement, planning, problem solving
Speech: speaking and writing (Broca’s area)
Body movement (motor strip)
Intelligence, concentration, self awareness

Question 13

Parietal lobe

Answer 13

Interprets language, words
Sense of touch, pain, temperature (sensory strip)
Interprets signals from vision, hearing, motor, sensory and memory
Spatial and visual perception

Question 14

Occipital lobe

Answer 14

Interprets vision (colour, light, movement)

Question 15

Temporal lobe

Answer 15

Understanding language (Wernicke’s area)
Memory
Hearing
Sequencing and organisation

Question 16

Cortex

Answer 16

The surface of the cerebrum is called the cortex.

Question 17

Hypothalamus

Answer 17

located in the floor of the third ventricle and is the master control of the autonomic system. It plays a role in controlling behaviours such as hunger, thirst, sleep, and sexual response. It also regulates body temperature, blood pressure, emotions, and secretion of hormones.

Question 18

Pituitary gland

Answer 18

The pituitary gland is connected to the hypothalamus of the brain by the pituitary stalk. Known as the “master gland,”
It controls other endocrine glands in the body. It secretes hormones that control sexual development, promote bone and muscle growth, and respond to stress.
