Hindbrain include the following,
EXCEPT:
a. brainstem
b. Spinal cord
c. cerebellum
It is the topmost section of the brain
stem.
a. hindbrain
b. Midbrain
c. forebrain
The biggest part of the brain is the
a. midbrain
b. cerebrum
c. cerebellum
These are the building blocks of the
nervous system
a. Spinal cord
b. Cerebral Cortex
c. Neuron
A typical neuron possesses a cell
body often called
a. nucleus
b. axon
c. soma
The ________ carries nerve signals
away from the soma
a. dendrites
b. axon
c. Nerve cell body
It convey information from tissues and

Neurons communicate with one
another via
a. junction
b. synapses
c. axons
The term neuron was coined by the
German anatomist ________.
a. Heinrich Wilhelm Waldeyer
b. Henry Louis "Lou" Gehrig
c. Guillaume-Benjamin-Amand Duchenne
It is inflammation of the protective
membranes covering the brain and
spinal cord, known collectively as
the meninges.
Meningitis
A condition which is characterized
by a protrusion of the meninges of
the brain or spinal cord through a
defect in the spinal cord.
Meningocele
Also known as "water on the brain,"
is a medical condition in which there
is an abnormal accumulation of
cerebrospinal fluid (CSF)
Hydrocephalus
It is the name given to a large group of
motor (body movement) disorders that
begin early in life and result from brain
injuries that are non-progressive (do
not worsen over time).
Cerebral Palsy
A type of cerebral palsy that is
synonymous with stiff or difficult
movement
Spastic
It is caused by a defect in a gene
inherited on the X chromosome.
Duchenne Muscular Dystrophy
It is a neurodevelopmental disorder
(a problem related to brain
development) that causes
hyperactivity, impulsive behaviour,
and attention problems.
ADHD
It is a neurological disorder caused
by damage to the portions of the
brain that are responsible for
language.
Aphasia
is the act of demyelinating, or the
loss of the myelin sheath insulating
the nerves.
Demyelination
is a neuromuscular disease leading
to fluctuating muscle weakness and
fatigability.
Myasthenia Gravis
How many pairs are there in cranial
nerves?
12
Meninges are composed of dura
mater, pia mater and
Arachnoid
True or False:
One estimate puts the human brain
at about 100 billion neurons and
100 trillion synapses.
True
True or False:
The spinal cord affects other neurons
by releasing a neurotransmitter that
binds to chemical receptors.
False
There are no neurons that lack a
soma, but there are neurons that
lack dendrites, and others that lack
an axon.
True
It begins at the Occipital bone and
extends down to the space between
the first and second lumbar
vertebrae
Spinal Cord
The human spinal cord is divided
into how many different segments?
31
These are endogenous chemicals
which transmit signals from a
neuron to a target cell across a
synapse
Neurotransmitters
Acetylcholine is distinguished as the
transmitter at the neuromuscular
junction connecting motor nerves to
muscles.
True
All neurons are electrically
excitable.
True
