|---|---|---|---|---|---|
| Explain the difference between the central nervous system and the peripheral nervous system. | Central = brain & spinal cord: peripheral - all parts of nervous system except spinal cord and brain
🗑
|
||||
| Explain what a dendrite does. | receives information from other cells within the body
🗑
|
||||
| Explain what a axon does. | carries nerve impulses away from the neuron to the next neuron
🗑
|
||||
| What is a neuron? | nerve cell that is specialized to receive and conduct electrical impulses.
🗑
|
||||
| What part of the nerve cell stores the nucleus and organelles? | Cell body
🗑
|
||||
| Which way does a nerve impulse flow from axon, dendrite and cell body? | dendrite ----> cell body -----> axon
🗑
|
||||
| Explain the differences between sensory and motor neurons. | sensory: gather information about what is happening in and around your body; motor: send impulses from brain & spinal cord to other systems.
🗑
|
||||
| Give examples of a sensory impulse. | receptors in eye detect light, receptors in ear sense vibrations, taste, smell
🗑
|
||||
| Give examples of a motor impulse. | muscles contracting (muscles get impulse from motor neurons); clapping your hands (impulses sent from brain to hands)
🗑
|
||||
| Where do sensory impulses travel to? | to the central nervous system
🗑
|
||||
| Where do motor impulses travel to? | to other systems in the body
🗑
|
||||
| What is a nerve? | it is a collection of axons bundled together with blood vessels and connective tissue.
🗑
|
||||
| Explain what a somatic nerve response would be. | responses you can control
🗑
|
||||
| Explain what an autonomic nerve response would be. | responses are automatic
🗑
|
||||
| Give examples of a somatic nerve response. | smiling, talking, jumping
🗑
|
||||
| Give examples of a autonomic nerve response. | digestion, breathing, heart rate
🗑
|
||||
| What is the brain? | main control center of the nervous system
🗑
|
||||
| Explain what the cerebrum does for your body. | where you think; most memories stored there - controls voluntary movements and lets you sense touch, light, sound, odors, taste, pain, heat and cold.
🗑
|
||||
| Explain what the cerebellum does for your body. | process sensory information from your body; allow brain to keep track of your body's position - so helps keep your balance.
🗑
|
||||
| Explain what the medulla does for your body. | connects to you spinal cord; controls involuntary processes like blood pressure, body temp, heart rate, etc.
🗑
|
||||
| What is the largest part of the brain? | cerebrum
🗑
|
||||
| What is the function of the spinal cord? | nerve fibers in your spinal cord lets your brain communicate with you peripheral nervous system.
🗑
|
||||
| List ares of the body where senses of touch occur, | skin - throughout our body
🗑
|
||||
| What is a reflex? | an involuntary and almost immediate movement in response to a stimulous - is autonomic
🗑
|
||||
| What part of the eye does light travel through? | the pupil and the lens
🗑
|
||||
| What is the function of the iris? | it controls the amount of light that enters the eye and gives the eye its color
🗑
|
||||
| On what part of the eye do you see images? | retina
🗑
|
||||
| What is the job of the lens? | to focus the light onto the retina so we can see image
🗑
|
||||
| What is farsighted? | lens focuses the light just behind the retina (can see far but not near)
🗑
|
||||
| What is nearsighted? | the lens focuses the light in front of the retina (can see near but not far)
🗑
|
||||
| What types of corrective lens corrects farsighted and then nearsighted? | convex lens (farsighted) bends light inward; concave lens (nearsighted) bends light rays outward
🗑
|
||||
| What part of the ear has tiny bones that vibrate sound? | the middle ear - parts are stirrup, hammer and anvil
🗑
|
||||
| What part of the ear receives sounds from the outside environment? | ear drum (tympanic membrane)
🗑
|
||||
| Explain the function of the cochlea. | changes sound waves into vibrations and then sends them to brain so you can hear
🗑
|
||||
| What type of sensor cell detects taste? | taste buds
🗑
|
||||
| What part of the tongue detects salt, sweet, sour and bitterness? | Sweet and salt is on the tip of the tongue; sour - middle/sides of tongue; and bitterness - in the back
🗑
|
||||
| The tiny bumps of the tongue that receive taste. | papillae
🗑
|
||||
| Explain the function of the endocrine system. | collection of glands that secrete hormones that regulate growth, development and homeostasis.
🗑
|
||||
| The organs of the endocrine system that produce chemicals for your body. | glands - thyroid, pituitary, thymus, pancreas
🗑
|
||||
| What are the chemicals of the glands called? | hormones
🗑
|
||||
| The type of hormone produce when someone becomes scared. | adrenaline/epinephrine
🗑
|
||||
| What is the function of the pituitary gland? | stimulates skeletal growth and helps thyroid gland work. - controls endocrine system
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
