|---|---|---|---|---|---|
| synapse | the location where one neuron transfers the impulse to another
🗑
|
||||
| cell body | The cell body, also called the soma, is the spherical part of the neuron that contains the nucleus. The cell body connects to the dendrites, which bring information to the neuron, and the axon, which sends information to other neurons.
🗑
|
||||
| axon | the long threadlike part of a nerve cell along which impulses are conducted from the cell body to other cells.
🗑
|
||||
| dendrite | a short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body.
a crystal or crystalline mass with a branching, treelike structure.
🗑
|
||||
| cerebrum | controls thought
🗑
|
||||
| cerebellum | controls the ability to balance
🗑
|
||||
| medulla | controls autonomic function
🗑
|
||||
| spinal cord | sends info to the brain
🗑
|
||||
| spinal nerves | receives the info ans sends it out if it needs to
🗑
|
||||
| central nervous system | the brain and the spinal cord, make up one of the two main parts of the nervous system
🗑
|
||||
| peripheral nervous system | Consists of sensory nerves and motor nerves, make up the second of the two main parts of the nervous system
🗑
|
||||
| sympathetic nervous system | the "up" system: dilates pupils, accelerates heart, dilates bronchi...
🗑
|
||||
| parasympathetic nervous system | the "down" system: constricts pupils, stimulates tear glands, slows heart, constricts bronchi...
🗑
|
||||
| the cerebral cortex | your thinking brain, convoluted (folded) to have more space
the large the cortex the smarter the species
🗑
|
||||
| the limbic system | "middle" section of the brain, emotional regulation & reaction
"your emotional brain"
🗑
|
||||
| interneurons | interconnect various neurons within the brain or the spinal cord
🗑
|
||||
| motor neurons | conduct motor commands from the cortex to the spinal cord or from the spinal cord to the muscles
🗑
|
||||
| sensory neurons | receive sensory signals from sensory organs and send them via short axons to the central nervous system
🗑
|
||||
| frontal lobe | motor control; concentration, planning and problem solving; speech; smell
🗑
|
||||
| parietal lobe | touch and pressure; taste; body awareness
🗑
|
||||
| occipital lobe | vision
🗑
|
||||
| temporal lobe | hearing; facial recognition
🗑
|
||||
| primary motor cortex | (on the frontal lobe) controls voluntary movement
🗑
|
||||
| primary auditory cortex | (on the temporal lobe) process auditory info
🗑
|
||||
| somatosensory cortex | (on parietal lobe) receives info on body sensations
🗑
|
||||
| primary visual cortex | (ob the occipital lobe) processes visual info
🗑
|
||||
| association areas | (on all four lobes) combine sensory and motor info coordinate between different brain areas
🗑

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.
