O central nervous system (CNS) is made up of brain and the spinal cord of vertebrates and plays a key role in controlling the body.
It is the system responsible for communication, reception of external stimuli, interpretation and transport of information from the body of vertebrates.

We prepared a list of exercises on central nervous system so you can test your knowledge.

1) (UECE) These are more differentiated cells with less reproduction capacity:
a) neurons.
b) lining epithelium.
c) hepatocytes.
d) fibroblasts.
2) Analyze the alternatives below and mark the one that no describes a function of the nervous system.
a) Capture and interpret stimuli from the environment.
b) Transport information.
c) Create answers through movements, sensations or observations.
3) (VUNESP) Imagine the following situations:
I – You are going to have an injection and your arm is distended, receiving the needle prick without any reaction.
II – You were distracted and someone pricked your arm with a pin; the reaction was a leap.
The organs of the nervous system that controlled the first and second reactions were, respectively:
a) spinal cord and brain.
b) cerebellum and cortex.
c) medulla and hypothalamus.
d) brain and spinal cord.
e) brain and neuron.
4) The nervous system is divided into central nervous system (CNS) and peripheral nervous system (PNS). Mark the alternative that contains the organs that are part of these systems.
a) CNS: brain and spinal cord; SNP: nerves and nerve ganglia.
b) CNS: brain and neurotransmitters; PNS: brainstem and dorsal roots.
c) CNS: nerves and nervous ganglia; PNS: brain and spinal cord.
d) CNS: cerebrum and cerebellum; PNS: diencephalon and spinal cord.
e) CNS: cerebrum and cerebellum; SNP nerve cells and neurotransmitters.
5) (CESGRANRIO) It is common to hear expressions such as: “My heart was racing”, “I was so nervous that I started to sweat”, “My mouth felt dry”. These reactions are characteristic of an altered emotional state, and are controlled under the action of (s):
a) autonomic nervous system.
b) somatic nervous system.
c) thyroid hormones.
d) nerves of the cerebellum.
e) medullary nerve center.
6) The cerebrum is a part of the brain that corresponds to approximately 80% of this structure and has a large number of grooves and depressions. Mark the alternative that correctly indicates some of the main functions of the brain:
a) The brain is related to the coordination of movements, balance and posture.
b) The brain is involved in regulating cardiovascular functions, controlling breathing and coughing and sneezing reflexes.
c) The brain is responsible for processing motor impulses and regulating body temperature.
d) The brain is related to language, emotional behavior and reasoning.
e) The brain is responsible for controlling hearing, blood pressure and breathing.
7) (Fuvest) Which of the following behaviors involves the greatest number of nervous system organs?
a) Salivating when smelling delicious food.
b) Raise the leg when the doctor touches the patient's knee with a hammer.
c) Blink with sudden approach of an object.
d) Abruptly withdraw your hand when touching a very hot object.
e) Complete an identification form.
8) The spinal cord is a cylindrical structure that extends from the foramen magnum to the second lumbar vertebra. This structure is related to simple and quick responses to certain stimuli, such as withdrawing your hand from a hot object. These responses are called spinal reflex responses.
Regarding medullary reflex responses, mark the correct alternative.
a) In this type of response, the brain quickly sends a stimulus, without the need for spinal cord interference.
b) The medulla quickly takes the stimulus to the brain which produces an extremely rapid reflex response.
c) In this process, there is no intervention of the brain, and the medulla is responsible for generating the response.
d) In spinal cord reflex responses, the brain generates a response and sends it to the spinal cord, which processes and responds to the stimulus.
9) To guarantee the protection of the central nervous system, three fibrous membranes surround the structures that compose it. What are these membranes called?
a) Amnios.
b) Pleura.
c) Cardias.
d) Meninges.
e) Fascias.
10) (UFRN) An offending driver, while driving on the Via Costeira, at high speed, lost control of the car on a curve, suffering an accident. Upon arrival at the emergency room, he was diagnosed with cerebral ischemia (blockage of circulation in the arteries that supply blood to the brain) in the frontal lobe of the brain.
As a result, the driver's ability to:
a) blink under the stimulus of an intense light.
b) salivate when smelling a food.
c) complete an identification form.
d) feel pain when touching a hot iron.
