Lesson Worksheet: The Central Nervous System Biology

In this worksheet, we will practice describing the structure and function of the different parts of the central nervous system.


The spinal cord is protected inside the canal.

  • Abony
  • Bneural
  • Ccordic
  • Dcentral


By examining the exterior of the cerebrum, In a hemisphere, how many lobes can be identified?

  • A6 lobes
  • B4 lobes
  • C5 lobes
  • D3 lobes


When you touch a tennis ball, you feel its rough texture with your skin. Which part of the brain is responsible for processing this kind of signal (nerve impulses)?

  • AThe frontal lobe
  • BThe cerebellum
  • CThe parietal lobe
  • DThe midbrain


A bump on someone’s head might make them see stars inside their eyes. The part of the brain that is most likely responsible for this phenomenon is the .

  • Amidbrain
  • Boccipital lobe
  • Cfifth lobe
  • Dcerebellum


The part of the brain which is mainly responsible for the regulation of body core temperature is located .

  • Ain the brain stem, in front of the cerebellum
  • Bbelow the thalamus and above the brainstem
  • Cat the front of each cerebral hemisphere and in front of the parietal lobe
  • Dbetween the forebrain and the hindbrain, deep within each cerebral hemisphere


The following diagram can be described as a .

  • Alateral view of both the hindbrain and the cerebral cortex, highlighting a part of the parietal lobe
  • Blateral view of the cerebellum, highlighting the fifth lobe of the brain
  • Ctop view of one cerebral hemisphere, highlighting one of the four main lobes of the brain
  • Dlateral view of both the forebrain, highlighting part of the frontal lobe, and the midbrain


The brain and the spinal cord, the two parts of the CNS, are both protected by meninges. Choose the correct statement regarding the layers of meninges protecting each of the brain and the spinal cord.

  • AThe brain is covered by dura mater, arachnoid, and pia mater, while the spinal cord is protected by the dorsal muscles, so it only needs the arachnoid and pia mater.
  • BThe spinal cord is covered by the dura mater, while the brain is not, due to the presence of the skull.
  • CThe brain is surrounded by dura mater and arachnoid only, which protect it against physical trauma, while the spinal cord is protected by dura mater, arachnoid, and pia mater.
  • DThe outer side of the dura mater surrounding the brain and the spinal cord is in contact with bony tissue.


What is the central nervous system comprised of?

  • AThe spine and the spinal nerves
  • BThe peripheral nerves in external limbs
  • CThe brain and the spinal cord
  • DThe brain and the cranial nerves


is the main part of the brain responsible for controlling and coordinating your movements and keeping your body balance when you exercise.

  • ACerebellum
  • BMedulla oblongata
  • CFrontal lobe
  • DMidbrain


What is the function of the medulla oblongata?

  • ATo receive and process auditory and visual information
  • BTo control voluntary movements and help with memory and speech
  • CTo control breathing, blood pressure, and heart rate
  • DTo control fine motor movements, posture, balance, and coordination
  • ETo store and release hormones produced by the hypothalamus
