Central Nervous System

Which of the following body organs or body parts is most likely associated with Central Nervous System and responsible for movement and balance?

Cerebellum The cerebellum is located under the cerebral hemispheres and is involved in movement coordination, balance and equilibrium and muscle tone.

Which lobe is involved in visual perception and color recognition?

Occipital Lobe The occipital lobe is located at the back region of the cerebral cortex and is involved in visual perception and color recognition.

The Central Nervous System's route of communication with the body is through which of the following?

Spinal Cord The spinal cord is a long bundle of nerves and support cells that extend from the brain. The function is to transmit neural signals from the brain to the rest of the body, but also independently control some reflex arcs.

Which of the following contains the nerve cell bodies of the afferent sensory spinal nerves?

Dorsal Root Ganglia The dorsal root ganglion contains nerve cell bodies that transmit signals from sensory appendages to the integration center. It is the nodule of the afferent sensory root of a spinal nerve.

Which of the following is involved in motor functions, reasoning, memory, and several higher order functions.?

Frontal Lobe The frontal lobe is located at the front of the brain and is involved in motor functions, reasoning, memory, and several higher order functions.

Unmyelinated axons are the components of which of the following?

Grey Matter Grey matter is typically associated with the outer tissue of the brain. It consists of dendrites, unmyelinated axons, glial cells (oligodendrocytes) and capillaries.

Which of the following is the lower half section of the brain-stem and is responsible for autonomic functions?

Medulla Oblongata The medulla oblongata is the lower half section of the brain-stem and is responsible for autonomic functions and systems, such as respiration, cardiac center, and bulbar reflexes including vomiting, swallowing, coughing and sneezing.

Which of the following Lobes integrates sensory information and determines spatial sense and navigation?

Parietal Lobe The parietal lobe is located above the occipital lobe and behind the frontal lobe. It integrates sensory information and determines spatial sense and navigation.

Which of the following is located between the Midbrain and the Medulla Oblongata?

Pons The pons is a portion of the hindbrain that bridges the medulla oblongata and cerebral cortex. It coordinates arousal, autonomic functions, sensory information and sleep.

Which of the following lobes has functions which include auditory perception, memory, speech, emotional responses, visual perception, and language skills including writing?

Temporal Lobe The temporal lobe is located in between the occipital and frontal lobes, beneath the parietal lobe. Its functions include auditory perception, memory, speech, emotional responses, visual perception, and language skills, including writing.

Glial cells and myelinated axons are the components of which of the following?

White Matter White matter is associated with inner brain tissue and consists mainly of glial cells and myelinated axons. White matter may affect how the brain learns and functions, as it modulates the distribution of action potentials and coordinates between different brain regions.
