EXAMINATION 2026 QUESTIONS WITH
ANSWERS GRADED A+
◍ true or false , if false explain why the statement is false: the central nervous
system consists of the brain and spinal cord.
Answer: true
◍ what causes an extremely high blood pressure in the glomeluar capillaries.
Answer: the difference in diameter causes very high bp which results in the
water and solutes to exit the blood and make their a inside of the glomeluar
capillaries which are known to filtrate
◍ describe the difference between the 2 types of nephrons.
Answer: 1. cortical nephrons which are in the cortex region of the kidney ,
with the exception of the loop of henle which extend to the medulla2. the
remaining nephrons, aka the juxtamedullary nephrons, pass deeply into the
medulla because ofbtheir location and their longer loops of henle
◍ a pt is unable to extend his left wrist or fingers. what never is most likely
damaged ?.
Answer: radial nerve
◍ Define systole.
Answer: Contraction of the heart
◍ what is the purpose of the blood brain barrier? describe its maintenance
from a cellular level.
Answer: it is a diffusion barrier that helps in the prevention of unneeded
materials that attack the CNS by keeping the brain and spinal cord away
from the general blood bank.It is composed of the gilal cells astrocytes and
its pertinent for regulation to be able to keep a homestatis which aids in
, protecting the neurons
◍ match the following lobes of the brain with the correct function.
Answer: temporal - contains sensory areas for hearing and smelling frontal-
contain higher levels ex..pariteal - receives sensory info from body receptors
occipital - interprets visual input
◍ a pt is admitted to the ER with hives and difficulty breathing. what is most
likely happening.
Answer: anaphylaxis
◍ This part of a reflex is inside the CNS, made up of one or more synapses..
Answer: integration center
◍ name the lymphatic vessel below highlighted in blue.
Answer: right lymphatic duct
◍ what's the purpose of the fossa avails in a fetus.
Answer: the fossa marks the place of opening between the atria which is
present in all growing fetuses. it permits blood to flow directly Erin the right
t the left atrium,. the fossa closes during birth so the lungs can gain access to
oxygen once the baby is born
◍ List the phases of an action potential in order.
Answer: 1. resting potential 2. depolarization3.repolarizarion4.resting
condition
◍ oxygenated blood is pumped from the heart through the ___ to the rest of
the body ..
Answer: left, systemic circuit
◍ what is true about the flexor withdrawl reflex.
Answer: A&d (IT DOES NOT INVOLVE INTERNEURONS & THE
EFFECT OF THE REFLEX IS TO CREATE A CO-CONTRACTION OF 2
MUSCLES
◍ name and describe what is occurring in the neurocell membrane in section 2
of the diagram. include the charge of the membrane during this phase.
