| Question | Answer |
|---|---|
| What do we call the body’s attempt to maintain a constant internal balance | Homeostasis |
| External or internal changes that cause a response are ______ | Stimuli |
| A response to stimuli that maintains the body’s internal balance is a form of this: | Homeostasis |
| What is the scientific name for a nerve cell? | Neuron |
| What are the three parts of a neuron? | Dendrite, Cell body, Axon |
| Which part of the neuron receives impulses and carries them TO the cell body? | Dendrite |
| Which part of the neuron carries impulses AWAY from the cell body to other neurons? | Axon |
| What are the two main types of neurons we studied? | Sensory neurons; Motor neurons |
| Which type of neuron sends impulses to the brain and spinal cord? | Sensory neuron |
| Which type of neuron relays information to the muscles and glands in the body? | Motor neuron |
| What do we call the space between the AXON of one neuron and the DENDRITE of the next? | Synapse |
| How are impulses transferred from one neuron to the next? | The axon carries the impulse to the dendrite of another neuron where it moves across the synapse. |
| What chemicals help impulses cross the synapse? | Neurotransmitters |
| Which nervous system is made up of the Brain and the Spinal Cord? | Central Nervous System |
| Which nervous system is made up of all the nerves in your head (not brain) and those coming off of the spinal cord? | Peripheral Nervous System |
| What are the three main parts of the brain? | Cerebrum, Cerebellum, Medulla |
| Which part of the brain is the largest and controls thinking and memory? | Cerebrum |
| Which part of the brain helps maintain balance and coordinate muscle movements? | Cerebellum |
| Which part of the brain controls involuntary actions like breathing, swallowing, and heartbeat? | Medulla |
| What name is given to the outer portion of the Cerebrum? | Cortex |
| What do the ridges and grooves of the cortex do? | increase surface area, allowing for complex thinking |
| After a brain injury, you have difficulty remembering things. What area of your brain was most likely damaged? | Cerebrum |
| After a brain injury, you frequently stumble, fall, and have difficulty with motor control. What area of your brain was most likely damaged? | Cerebellum |
| After a brain injury, you have difficulty swallowing. What area of your brain was most likely damaged? | Medulla |
| After a brain injury, you cannot answer simple questions. What area of your brain was most likely damaged? | Cerebrum |
| After a brain injury, your heart stops beating, and you don’t breathe on your own. What area of your brain was most likely damaged? | Medulla |
| What connects the base of the brain to the spinal cord | Brain Stem |
| What organ carries impulses between the body and the brain? | Spinal Cord |
| How thick is the spinal cord? | About as thick as an adult thumb |
| What is an involuntary response to a stimulus? | Reflex |
| True or False: Drugs can directly affect the nervous system | True |
| Drugs can destroy cells in these organs: | Brain and Liver |
| What kind of drug slows down responses in the Central Nervous System, as well as thinking processes? | Depressant |
| What kind of drug speeds up heart rate, causes sleeplessness, and can increase urine output? | Stimulant |
| What begins when a object vibrates, causing air particles to push on each other and transfer energy? | Sound |
| What is the path of sound through the ear (3 stages)? | outer ear-->middle ear-->cochlea of the inner ear |
| What do we call the vibrations that cause sound? | Sound waves |
| How does sound move from the outer to the middle ear? | Tiny bones connected to the eardrum vibrate |
| These convert waves to electrical impulses and send them to the part of the brain that interprets sound: | Neurons in the cochlea |
| What sensory receptors are located in the papillae? | Taste buds |
| What are the four taste sensations that combine to make up all flavors? | Sweet, sour, salty, bitter |
| What receptors for smell are located in the upper part of your nasal cavity? | Olfactory cells |
| Information from what two sets of receptors combines in the brain to give the sense of smell? | Taste buds and olfactory cells |
