UBSON - ANAPHY CENTRAL NERVOUS SYSTEM

What are the two main divisions of the nervous system?

• Sympathetic and Parasympathetic

• Motor and Sensory

• Autonomic and Somatic

• Central and Peripheral

Answer explanation

The two main divisions of the nervous system are Central and Peripheral, which encompass the brain, spinal cord, and nerves outside the central nervous system.

Which part of the brain is considered the single most complex object in the known universe?

• Thalamus

• Cerebrum

• Cerebellum

• Brain Stem

Answer explanation

The Cerebrum is considered the single most complex object in the known universe due to its intricate structure and functions such as cognition, sensory perception, and voluntary movement.

What are the three primary brain vesicles that demarcate early brain development?

• Cerebrum, Brain Stem, Cerebellum

• Telencephalon, Diencephalon, Metencephalon

• Prosencephalon, Mesencephalon, Rhombencephalon

• Forebrain, Midbrain, Hindbrain

Answer explanation

The three primary brain vesicles that demarcate early brain development are Prosencephalon, Mesencephalon, Rhombencephalon.

Which region of the brain regulates muscle contraction to generate smooth, coordinated motion?

• Cerebrum

• Brain Stem

• Cerebellum

• Thalamus

Answer explanation

The region of the brain that regulates muscle contraction to generate smooth, coordinated motion is the Cerebellum.

What is the function of the thalamus in the brain?

• Receives and directs information to the cerebral cortex

• Processes odors

• Controls voluntary motion

• Regulates body temperature

Answer explanation

The thalamus in the brain receives and directs information to the cerebral cortex, making it the correct function of the thalamus.

Which area of the brain controls muscles involved in speech production?

• Primary Cortex

• Premotor Cortex

• Broca's Area

• Frontal Eye Field

Answer explanation

Broca's Area in the brain controls muscles involved in speech production.

What is the primary function of the hypothalamus?

• Controls voluntary motion

• Regulates body temperature

• Processes odors

• Receives and directs information to the cerebral cortex

Answer explanation

The primary function of the hypothalamus is to regulate body temperature, making it the correct choice among the options provided.

Which part of the brain is responsible for the conscious mind?

• Cerebellum

• Brain Stem

• Cerebrum

• Thalamus

Answer explanation

The cerebrum is responsible for the conscious mind, making it the correct choice out of the options provided.

What is the role of the primary somatosensory cortex in the brain?

• Controls voluntary motion

• Plans movements

• Processes odors

• Receives information from receptors in the skin

Answer explanation

The primary somatosensory cortex in the brain receives information from receptors in the skin, allowing for the perception of touch, pressure, temperature, and pain.

Which part of the brain is involved in planning movements and sequencing them into complex tasks?

• Broca's Area

• Premotor Cortex

• Frontal Eye Field

• Primary Cortex

Answer explanation

The Premotor Cortex is involved in planning movements and sequencing them into complex tasks.
