01 Oct The ventral horn sends efferent information from the CNS to the body via the ventral root.
Human Anatomy and Physiology I
The ventral horn sends efferent information from the CNS to the body via the ventral root.
T True
2. False
Question 2Which statement is true regarding the cerebrospinal fluid (CSF)?
CSF is produced by choroid plexus in the ventricles of the brain
CSF is only found within and around the brain
A function of the CSF is to control the blood flow into and out of the central nervous system
CSF is reabsorbed by the dura mater
Question 3Which part or region of the brain controls and is associated with perceiving information from the general sensory receptors in the skin such as the perception of touch?
Limbic system
Frontal lobe
Parietal lobe
Wernicke’s region
Question 4Which of the following is considered an ascending tract?
Anterior corticospinal tract
Lateral corticospinal tract
Spinothalamic tract
Vestibulospinal tract
Question 5Which part or region of the brain controls and is associated us to control the conscious movement of skeletal muscles?
Question 6Which choice is true regarding the brain stem? Choose all that apply.
One of the pons functions is to control behavior and emotion.
The pons contains nuclei centers that control actions like heart rate, respiratory rate and coughing
The limbic system is part of the medulla
The midbrain contains visual and auditory reflex centers
Question 7The right hemisphere of the brain is primarily responsible for analytical thought and rational thought.
True
False
Question 8Which statement is true regarding the meninges?
The subarachnoid space is filled with cerebrospinal fluid
The meninges forms a portion of blood brain barrier
Prescription medications can easily pass through the meninges to treat brain conditions
The arachnoid mater is attached directly to the cerebral cortex.
Question 9Which choice best describes the effect of destruction of the ventral (anterior) horns neurons in the spinal cord?
Loss of transmission of motor information/input to body
Inability to perceive pain
Loss of transmission of sensory information/input from body
Inability to transmit information to the brain
Question 10Which part or region of the brain controls and is associated the ability for speech production?
Parietal lobe
Wernicke’s region
Limbic system
Broca region
Question 11Which statement is true of the central nervous system?
Cerebral cortex is only found in the frontal lobe
White matter of the brain are specialized neurons that assist in vision processing
The pia mater of the meninges adheres directly to the brain and spinal cord
The ventricles of the brain help transmit information from one area of the brain to the other
Question 12The white matter of the spinal cord contains ascending tracts and the grey matter contains descending tracts.
True
False
Question 13Which of the following statements is true?
The cauda equine can be found in the thoracic spine.
White matter is found in the dorsal horn and ventral horn of the spinal cord.
White matter in the spinal cord is arranged into “columns”.
The spinal cord terminates at L5, just above the sacrum.
Question 14Cerebral spinal fluid (CSF) is located in which region?
Between the pia mater and nervous tissue
Subdural space
Subarachnoid space
Superficial to the dura mater
Question 15The thalamus helps regulate sensations, learning, memory, and motor activities.
True
False
Question 16Gyri and sulci can be found in which of the following structures?
Midbrain
Cerebral cortex
Pons
Thalamus
Question 17Which of these choices is the deepest layer of the meninges?
Dura mater
Arachnoid mater
Cranial mater
Pia mater
Question 18What part of the brain controls and is associated with body posture, balance, and equilibrium along with coordination of motor activity?
Medulla
Frontal lobe
Cerebellum
Occipital lobe
Question 19In reference to the spinal cord, both the anterior horn and posterior horn carry afferent neurons.
True
False
Question 20The cerebellum is responsible for sense of balance, proprioception, coordination, and precision movement.
True
False
Question 21Which statement is true regarding the spinal cord?
The lower lumbar region doesn’t contain a spinal cord but rather a collection of nerve roots called the cauda equina
The spinal cord terminates into the upper thoracic region
The anterior horns of the spinal cord receive information from the body
The spinal cord is surrounded by the dura mater only
Question 22Most neural pathways entering the spinal cord from left spinal nerves at some point desiccate (cross over) and are perceived by the right side of the cerebrum.
True
False
Question 23Which of the following assists in regulation of body temperature and food/water intake?
Pons
Frontal lobe
Occipital lobe
Hypothalamus
Question 24An epidural will puncture through the meninges to inject medication or extract cerebral spinal fluid.
True
False
Question 25Which statement is true regarding the spinal nerve and cord?
The dorsal root of the spinal nerves transmit (carry) information from the central nervous system out to the body
As a spinal nerve approaches the spinal cord, it separates into lateral and medial roots
A spinal nerve a single sensory axon and single motor axon
Spinal nerves exit the spinal cord through the intervertebral foramen of the vertebrae
