500
a) What is the job of Sensory Nerves?
b) What do the Motor Nerves do?
a) Sensory nerves deliver INPUT front he skin, ears, eyes, nose, and taste buds.
b) Motor nerves create OUTPUT by stimulating effectors; the three types of muscle: smooth, cardiac, and skeletal muscles.
500
a) What are the two branches of the Autonomic system?
b) What is the difference between the two?
a) The Parasympathetic branch and the Sympathetic branch.
b) The Parasympathetic branch controls "Resting and Digesting" (normal bodily functions); while the Sympathetic branch controls "Fight or Flight" (body's alert system).
500
What does the CNS do?
The CNS controls basic bodily functions and responds to external changes.
500
a) What kind of nerve is the Vagus Nerve? What does it control?
b) What kind of nerve is the Glossopharyngeal nerve? What does it
a) The Vagus nerve is a mixed nerve (both sensory and motor) nerve. It controls the muscles of the pharynx, larynx, stimulates muscles of organs in the thoracic cavity (heart) and abdominal cavity (intestines).
b) The Glossopharyngeal nerve is a mixed nerve. It controls the sense of taste (back of tongue) and voluntary movement of the throat used in swallowing.
1000
a) What is the blue portion of the brain called?
b) What is the green portion of the brain called?
a) The Frontal Lobe.
b) The Temporal Lobe.
1000
What are the four main functions of the Nervous system?
The Nervous System controls the body’s internal environment to maintain homeostasis; controls reflexes; Memory and learning; and voluntary control over movement.
1000
Two systems included in the Nervous System
What are the Central Nervous System (CNS) and Peripheral Nervous System (PNS)?
1000
What does the CNS consist of?
The CNS is the Brain and spinal cord
1000
a) What sensory nerve has control over smell?
b) What sensory nerve has control over vision/sight?
c) What sensory nerve has control over hearing and balance?
a) Olfactory is the sensory nerve for smell
b) Optic is the sensory nerve for vision/sight
c) Vestibulocochlear/Acoustic is the sensory nerve for hearing and balance. (Detects movement of the head)
1500
a) What is the Parietal lobe in charge of?
b) What does the Temporal lobe control?
a) The Parietal lobe is in charge of making sense of the world, perception, arithmetic, and spelling.
b) The Temporal lobe controls memory, understanding, and language.

Real Life situation: There’s a large, aggressive dog running towards you. It’s barking and running fast. Which branch of the ANS has been activated? Why?
The Sympathetic branch is activated because it is the body’s alert system; meaning the Fight or flight is activated. The sense of danger; the harder breathing, sweating, etc sends signals throughout your body, and it starts producing adrenaline.
1500
a) What type of neuron transmits information from the eyes and nose to the brain?
b) What are the sensory neurons in the body that receives information and transmits it back to the CNS?
c) What are the neurons found only in the brain?
a) Bipolar neurons
b) Unipolar neurons
c) Anaxonic neurons
1500
What are the three functions of the CNS?
The CNS controls sensory input, information processing, and motor output.
1500
a) On the diagram, what is number 6?
b) On the diagram, what number 5?
a) Abducens Nerve - motor nerve that controls the lateral rectus muscle for lateral eye movement.
b) Trigeminal - Mixed nerve that controls chewing and movement, sensation in the face and teeth
2000
There’s two other lobes that control movement and sensations. What are the names?
The Motor Cortex and Sensory Cortex.
2000
Where are the Meninges? What do they do?
Meninges are protective coverings on the brain and spinal cord. They act as shock absorbers and cushions.
2000
What are the six parts of the Human Brain?
The Frontal lobe, Parietal lobe, Occipital lobe, Temporal lobe, Cerebellum, and Brain Stem are the six main parts of the brain.
2000
What section of the CNS controls the area from your neck to your fingertips?
Your cervical partition of your Vertebral column; C1-C8.
2000
a) What number on the diagram represents the Accessory nerve?
b) What number on the diagram represents the Hypoglossal nerve?
c) What number on the diagram represents the Acoustic nerve?
a) #11
b) #12
c) #8
2500
a) What section of the vertebral column has 12 total vertebrae?
b) What section of the vertebral column has 5 vertebrae?
c) What section of the vertebral column has 7 vertebrae?
a) Thoracic Vertebrae has 12 vertebrae
b) Lumbar Vertebrae has 5 vertebrae
c) Cervical Vertebrae has 7 vertebrae.
2500
a) What does the Somatic Nervous System branch off of and control?
b)What does the Autonomic Nervous System branch off of and control?
a) The Somatic Nervous System is a branch off of the PNS. It controls skeletal muscle and voluntary movement (under conscious control)
b)The Autonomic nervous System (ANS) is another branch off of the PNS. It controls smooth and cardiac muscle in organs, blood vessels, airways, and several glands.
2500
a) What are the 5 sections of the Vertebral column?
b) What are some ways to avoid traumatic spinal injuries?
c) What are the three layers of the meninges? And what acronym can be used to remember them?
a) Cervical, Thoracic, Lumbar, Sacrum, and the Coccyx.
b) Some ways include:
Avoid drugs and alcohol
Safe use of motor vehicles
Safe swimming
Safe handling and storage of firearms
c) The Dura Mater - outer layer; the Arachnoid Mater - middle layer; and the Pia Mater - innermost layer. Can also be remembered as PAD
