Basic Ear Anatomy Worksheet

1.



2. What is the function of the following:
Pinna-Directs sound waves into the auditory canal.
Tympanic membrane-Turns the sound waves into sound vibrations.
Ossicles-Magnify the sound vibrations
Cochlea-Movement of fluids
Semicircular canals-Balance of the body, sends impulses to the brain to let it know your body is off balance, your brain would then send a message out for your body to correct itself.



3. What three bones make up the ossicles? The malleus, the incus, and the stapes.



4. What is the function of hairs in the ear? They stimulate nerve impulses to be sent to the brain by way of the auditory nerve.

Basic Nervous System Anatomy

1. What does CNS and PNS stand for? CNS-Central Nervous System; PNS-Peripheral Nervous System
2. What are the parts of the CNS? Brain and spinal cord.
3. Describe something that you do on a regular basis that your PNS controls. Maintain digestion.
4. What are the two divisions of the autonomic nervous system and what does each control? Sympathetic-controls the body in times of stress, worry, fear, and emergency. Parasympathetic-brings the body back to a normal state and allows for rest and relaxation to occur.
5. What are the three main types of neurons? What is the function of each? Sensory Neuron-sends a message to your brain to tell you when something hurts etc.; Motor Neuron-Carries the impulse from the CNS to your muscle for an action Interneuron-Converts the impulse through the CNS
6. What is the function of the axon of a nerve cell? The dendrite? The axon is the sending end of a neuron and a dendrite is the receiving end.
7. What is a synapse? The sparking or jumping of a neural impulse from one neuron to another.
8. Sketch a neuron and label the axon and the dendrite.
