Total questions: 30
Worksheet time: 1hrs 28mins
The following apply to the 11th cranial nerve, EXCEPT:
Lifting the shoulders up toward the ear then resisting the movement from above tests the trapezius
This combined motor and sensory nerve innervates the sternocleidomastoid and the upper portion of the trapezius muscle
Testing the function of the 11th nerve also tests for involvement of functions by motor neuron disease and dystrophy
Testing the function of the 11th nerve will detect weakness of either central or peripheral nuclei of origin
All of the following statements are true, EXCEPT:
Nerve impulses are propagated by the continuous progression of the action potential along the length of the fiber in myelinated fibers
Nerves with larger axons have lower stimulus thresholds for development of an action potential than do nerves with smaller axons
Nerves with large-diameter axons have greater conduction velocities than do nerves with smaller diameter axons
Conduction velocity is also substantially greater in myelinated axons than in unmyelinated axons
Stimulation of the anterior hypothalamus causes all of the following, EXCEPT:
Sweating
cutaneous vasodilation
increased respiratory rate
shivering
Deep tendon reflexes are:
polysynaptic nerve response
excitatory transmission
monosynaptic reflex response
bisynaptic reflex response
A pathway of communication between the two hemisphere is created as these fibers cross the midline from one hemisphere to the other:
transhemisphere
projection
commissural
association
Nerve cells at rest are positively charged on the outside and negatively charged on the inside
active potentials
action potential
hyperpolarization
resting membrane potential
. This great parasympathetic nerve supplies the thorax and abdomen:
abducens
hypoglossal
pelvic sphlanic
vagus
The sensory cranial nerve supply of the eyeball is:
4th
3rd
6th
opthalmic division of the fifth cranial nerve
What is a symptom of a stroke?
Hemiplegia of one body part
Aphasia of the face
Numbness of the hand
All of the above
What acronym can help you identify a stroke?
SLOW
FAST
STROKE
SLEEP
What is a stroke?
Blocked blood vessel
Bleeding in the brain from a blood vessel
Loss of oxygen to part of the brain
All of the above
A stroke happens when
when there is enough oxygen getting to the brain.
when there is a lack of oxygen getting to the brain.
Both of them
Use FAST to recognise the signs of a stroke. F is For ..........
Face mask
Face drooping
Face injury
As organisms get more complex, cells become specialized to perform specific functions in the body. What is the function for the cell shown?
contract and shorten movement
provide coverage and protection
carry impulses around the body
connects parts together
The human brain is made of 100 billion neurons. Each neuron has a nucleus that contains genes. Many neurons bind together to form a nerve.
tissue
system
organ
cell
The function of sneezing is to expel mucus containing foreign particles from the nasal cavity. A person sneezes when foreign particles pass through the nasal hair which triggers the release of chemical that activates body system causing sneezing. What body part is activated?
circulatory system
digestive system
nervous system
excretory system
The urinary bladder is a muscular organ of the excretory system that collects urine excreted by the kidney. How does the nervous system help the urinary system in excretion?
it signals the urinary bladder to absorb more water from the urine.
It signals the urinary system to collect waste from the different parts of the body.
It signals the urinary bladder to hold and release urine at appropriate times.
It signals the urinary bladder to allow more urine to flow from the ureters.
The brain has 3 major sections that send and receive signals to control all the activities that keep a person functioning efficiently. Which major section controls breathing and heart beat?
cerebellum
cerebrum
brain stem
cortex
Which 2 body systems interact and initiate movement?
muscular and nervous system
skeletal and muscular system
respiratory and nervous system
circulatory and nervous system
