Nervous system QMP Flashcards
The stage in action potential that immediately follows deploarization is
polarization the latent stage repolarization hyperpolarization the resting stage
repolarization
Often a Grand Mal fit will leave the individual feeling
As univentful as pre aura
Nauseated
Sleepy and disorientated, needing rest
Emotional tearful
Lively and excitable, needing something to do
Sleepy and disorientated, needing rest
Small masses of nervous tissue, consisting primarily of neuron cell bodies, found in the peripheral nervous system are called
neuclei nerves tracts horns ganglia
ganglia
The cardiovascular centre, which controls the rate and force of the heartbeat and diameter of blood vessels, is located in the
medulla oblongata insula diencephalon cerebrum pons
medulla oblongata
Behaviour arrest is sometimes called
A fit Aura Grand mal Petit mal Trans ischaemic attack
Petit mal
The process in which the strength of a sensation decreases during a prolonged stimulation is called
refraction relaxation adaptation accommodation consolidation
adaptation
During the creation of an action potential, deplorization of a membrane begins with the
opening of sodium channels
opening of cholride channels
closing of sodium channels
opening of potassium channels
opening of potassium channels
opening of sodium channels
The class of sensory receptors that are structurally the simplest are
proprioceptors free nerve endings encapsulated nerve endings seperate cells none of the above
free nerve endings
Processes that carry impulses from the neuron cell body to another neuron or effector are called
dendrites synapses myelin sheaths axons neurofibrils
axons
All of the following are mechanorecptors EXCEPT
lamellate corpuscles
hair root plexus
corpuscles of touch
type II cutaneous mechanotreceptors
cold receptors
cold receptors
The portion of the brain stem that is continuous with the spinal cord is the
cerebrum midbrain medulla oblongata cerebellum pons
medulla oblongata
Neurons that conduct nerve impulses from the receptors to the central nervous system are
sensory neurons
interneurons
motor neurons
associated neurons
efferent neurons
sensory neurons
The cause of a seizure is described as a
A clot in the lungs
A sudden uncontrolled electrical disturbance in the brain
Hypoxia
A sudden loss of necessary blood pressure in the glomerular vessels
A sudden blockage or bleed in the brain vasculature
A sudden uncontrolled electrical disturbance in the brain
The subarachnoid space is located between the
arachnoid mater and pia mater
bone and pia mater
arachnoid mater and dura mater
bone ans arachnoid mater
dura mater and pia mater
arachnoid mater and pia mater
Pressure receptors that consist of a large oval shaped, multilayered connectiove tissue capsule that encloses a dendrite are called
hair root plexuses
type II cutaneous mechanorecptors
nocirecptors
corpuscles of touch
lamellate corpuscles
lamellate corpuscles
Which of the following is an example of an effector?
interneuron special sense organ nerve glands sensory receptor
glands
Olfactory receptors
are located in the nasal cavity
have knob-shaped dendrites containing olfactory hairs
adapt rapidly
stimulated by inhaled chemicals
all of the above
all of the above
Muscle spindles are examples of
lamellate corpuscles hair cells proprioceptors nociceptors free nerve endings
proprioceptors
The sense that tells us which muscles are contracted, the amount of tension in a joint, the position of the joints, the orientation of the head is called
adaptation touch reception gustation proprioception nociception
proprioception
The most common triggers for seizure in people with epilepsy
quiet open spaces
closed in areas
Salt, glucose and greasy meals
Alcohol, loud noises and bright lights
Exercise
Alcohol, loud noises and bright lights
The following list contains an action you should NOT do during your patients seizure
loosen tight clothing especially around the neck
Monitor their airway
Stay with the patient
Restrain the patient as their movements are chaotic
Place in the recovery position away from harm
Restrain the patient as their movements are chaotic
The sensory receptors that respond to tastants in food are called
hair cells taste pores gustatory receptors photorecptors olfactory receptors
gustatory receptors
The tonic phase of a seizure
The preseizure phase that is described by patients as a warning
The shallow breathing after a seizure
A floppy phase where muscle activity is absent
The beginning of a seizure where the individual becomes rigid
Motor seizures using libs in erratic form
The beginning of a seizure where the individual becomes rigid
One of the following diagnostic procedures is NOT used to diagnose epilepsy
ECG Skull x-ray EEG PET scan MRI scan
ECG
Tonic phase of a seizure often involves
shallow breathing Floppy and nonresponsive Vacant and still Back arching Lack of muscle tone - floppy
Back arching
Treatment for epilepsy is dependent on the cause, however certain tratments are recommended for controlling seizures, which one of the following is NOT a treatment for epilepsy.
EEG
Anticoonvulsant medication - Sodium Valproate
Surgery
Anticonvulsant medication - Carbamazepine
Surgical intervention alongside anticonvulsant
medication
EEG
The term hyperkinetic means
The twitching phase early in a grand mal fit
Motor seizures involving predominatly limb movements of high force
A floppy phase whereby there is no muscle activity
A rigid phase of a seizure
A jerking phase of a seizure
Motor seizures involving predominatly limb movements of high force
