A&P - Central Nervous System
What part of the brain controls and is associated with body posture, balance, and equilibrium along with coordination of motor activity?
Cerebellum
Which of the following is considered an ascending tract? Vestibulospinal tract. Anterior corticospinal tract. Spinothalamic tract. Lateral corticospinal tract.
Spinothalamic tract
Which part or region of the brain controls and is associated the ability for speech production?
Broca Region
Which 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. CSF is reabsorbed by the dura mater. A function of the CSF is to control the blood flow into and out of the central nervous system.
CSF is produced by choroid plexus in the ventricles of the brain.
The blood brain barrier helps minimize harmful substances from entering brain tissue. The blood brain barrier is made up of the _____.
Capillary walls and astrocytes
You are observing a neurological exam. The patient is having difficulty tandem walking. Tandem walking evaluates ______ .
Cerebellar function
Gyri and sulci can be found in which of the following structures?
Cerebral cortex
T/F: An epidural will puncture through the meninges to inject medication or extract cerebral spinal fluid.
False
T/F: In reference to the spinal cord, both the anterior horn and posterior horn carry afferent neurons.
False
T/F: The right hemisphere of the brain is primarily responsible for analytical thought and rational thought.
False
T/F: The white matter of the spinal cord contains ascending tracts and the grey matter contains descending tracts.
False
Which part or region of the brain controls and is associated with the conscious movement of skeletal muscles?
Frontal Lobe
Which of the following assists in regulation of body temperature and food/water intake? Occipital lobe Frontal lobe Pons Hypothalamus
Hypothalamus
Which 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. Inability to transmit information to the brain. Loss of transmission of sensory information/input from body.
Loss of transmission of motor information/input to body
Which of these brain structures is most superior? Temporal lobe Pons Parietal lobe Spinal cord
Parietal lobe
Which 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?
Parietal lobe
Which of these choices is the deepest layer of the meninges? Arachnoid mater Dura mater Pia mater Cranial mater
Pia Mater
Which of the following pathways handles motor signals? Posterior column Spinothalamic Spinocerebellar Pyramidal
Pyramidal
Which 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. A spinal nerve a single sensory axon and single motor axon. As a spinal nerve approaches the spinal cord, it separates into lateral and medial roots. Spinal nerves exit the spinal cord through the intervertebral foramen of the vertebrae.
Spinal nerves exit the spinal cord through the intervertebral foramen of the vertebrae.
Cerebral spinal fluid (CSF) is located in which region?
Subarachnoid space
Which 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 spinal cord is surrounded by the dura mater only. The anterior horns of the spinal cord receive information from the body.
The lower lumbar region doesn't contain a spinal cord but rather a collection of nerve roots called the cauda equina.
Which choice is true regarding the brain stem? 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. One of the pons functions is to control behavior and emotion..
The midbrain contains visual and auditory reflex centers.
Which statement is true of the central nervous system? 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. White matter of the brain are specialized neurons that assist in vision processing. Cerebral cortex is only found in the frontal lobe.
The pia mater of the meninges adheres directly to the brain and spinal cord.
Which statement is true regarding the meninges? The arachnoid mater is attached directly to the cerebral cortex. The meninges forms a portion of blood brain barrier. The subarachnoid space is filled with cerebrospinal fluid. Prescription medications can easily pass through the meninges to treat brain conditions.
The subarachnoid space is filled with cerebrospinal fluid.
T/F: Most 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
T/F: The cerebellum is responsible for sense of balance, proprioception, coordination, and precision movement.
True
T/F: The spinal cord's posterior column of white matter is comprised of sensory tracts.
True
T/F: The thalamus helps regulate sensations, learning, memory, and motor activities.
True
T/F: The ventral horn sends efferent information from the CNS to the body via the ventral root.
True
You are observing a neurological exam. The patient has a positive pronator drift. This is a sign of ____.
Upper motor neuron dysfunction
Which 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.
White matter in the spinal cord is arranged into "columns".
