Total questions: 61
Worksheet time: 10mins
The ability of taking notes and respond to various factors in the surrounding world depends on the (a) system
The central nervous system consists of the brain and the (a) cord
(a) nerves are connected with the brain and the spinal cord
Twelve cranial nerves serve mostly the (a) organs
(a) system is a part of the body's communication network
The automatic system affects the automatic and (a) actions of the internal organs.
The nervous system also has the function of picking up (a) of light, sound, touch, taste, heat, cold, pain etc ...
The sensations are carried from sense organs to the (a) over the sensory nerves
The brain receives messages and reacts to them, makes plans and sends (a) for action
Orders of the brain are carried to the muscles by the (a) nerves
What is the control center of the entire nervous system?
the brain
the spinal cord
the nerves
the muscles
What is the brain?
a soft, spongy mass of tissue
the bones of the cranium
nervous tissue
gray matter and white matter
The brain is surrounded and protected by the bones of the (a)
The brain and the spinal cord consist of two kinds of nervous tissue called (a) matter and white matter
Gray matter consists largely of nerve cell (a)
white matter is made up of nerve (a)
What is the basic unit of the nervous system?
nerve cell
neuron
nerve cell or neuron
nucleus
All neurons are distinguished from other body cells by thin fibers or (a)
The extensions are called dendrites or (a)
Dendrites are the part of the nerve cell that receive (a)
The stimulus passes into the nerve cell and then into the (a)
The axon carries the stimulus along to the (a) of another nerve cell
The nerve cells communicate their impulse chemically across gaps called (a)
If the tiny cell body is destroyed, it .......... be repaired
can
can't
If an axon or dendrite is cut, it will often (a) and function again
What is the function of the sensory nerves?
carry stimuli from the various sense organs to the brain.
carry impulses from the brain or other nerve centers to the muscles
serve as the connections between each other and between sensory and motor nerves
What is the function of the motor nerves?
carry stimuli from the various sense organs to the brain
carry impulses from the brain or other nerve centers to the muscles
connect the nerves
The nervous system helps us ........
take notes and respond to factors in the surrounding world
meet or even touch each other at their points of connection
control center of the entire nervous system
It is owing to the nervous system that we can take notes and respond to our surrounding world.
