Identify the following:

Write:

A- cerebrum

B- cerebellum

True or False:

Joy’s doctor prescribed her antibiotics for a week due to persistent skin allergy. After a week, she still takes the same medicine thinking that it will suppress her allergy from attacking again.

1. Improper use of antibiotics often leads to deafness. Therefore it destroys the sensory neurons/receptors in the ears that receive sound waves.

True

True or False:

Joy’s doctor prescribed her antibiotics for a week due to persistent skin allergy. After a week, she still takes the same medicine thinking that it will suppress her allergy from attacking again.

2. If she becomes deaf, she can’t “interpret” the sound. Sound does not reach her cerebellum.

False

True or False:

Christopher suffered from spinal cord injury after his car accident. This rendered him immobile and impaired his sensations.

3. He cannot distinguish whether a substance is cold or hot. His injury affected his parietal lobe.

True

True or False:


4. The accident caused him immobile. This severely affected his cerebellum.

True

True or False:


5. He cries everytime he remembers the happy days when his body was still able. This is stimulated by brain stem.

False

True or False:


6. The accident numbed his senses. This impaired his cerebrum.

True

True or False:

Gwen suffered from a major stroke caused by high cholesterol level blocking her major artery in the heart. She has been in coma for several months.

7. The nerve cells in her brain will undergo mitosis after her coma state.

False

True or False:

Jonathan broke the bone in his leg after his basketball tournament. He is now recuperating from injury.

10.The cerebellum will remain functional after recuperating from injury.

True

True or False:


11. This condition is an example of a reflex action.

False

True or False:


12. The sensory neurons in his legs will no longer transmit sensation to the brain.

False

Path of the Nerve Impulse

Explain how a message is transmitted to and from the brain by arranging

the events in the correct order.

A. The sensory receptors in the boy’s nose are stimulated by the chemicals from the burning rag.

B. The nerve impulse travels from one neuron to another until it reaches the spinal cord.

C. The brain interprets the message as ”a rag is burning”.D. The motor neurons send a message to the leg and arm

muscles.E. The sensory receptors in the boy’s eyes are stimulated by

light from the burning rag.F. The message is received by the brain.G. The axon conducts the message away from the cell body.H. The boy’s arm move to put out the fire.I. The dendrites of a sensory neuron pick up the message and

conduct it toward the cell body.J. The leg muscles contract. The boy starts running toward

the burning rag.

1/2 A. The sensory receptors in the boy’s nose are stimulated by the chemicals from the burning rag.

7 B. The nerve impulse travels from one neuron to another until it reaches the spinal cord.

6 C. The brain interprets the message as ”a rag is burning”. 8 D. The motor neurons send a message to the leg and arm muscles.1/2 E. The sensory receptors in the boy’s eyes are stimulated by light

from the burning rag. 5 F. The message is received by the brain. 4 G. The axon conducts the message away from the cell body.9/10 H. The boy’s arm move to put out the fire. 3 I. The dendrites of a sensory neuron pick up the message and

conduct it toward the cell body.9/10 J. The leg muscles contract. The boy starts running toward the
