8.1 Nervous System Questions - Group 1 Flashcards
(23 cards)
What types of cells are responsible for transmitting electrical signals to other types of cells?
Neurons
What types of cells are found in the nervous system that cannot conduct nerve impulses but serve as “helpers” to neurons?
Neuroglia (glia cells)
This type of neuron brings information about what is happening in the environment to the brain and spinal cord.
Sensory Neuron
(also can be called an afferent neuron)
The ability to process information, store the information for future use, and to make decision is the function called:
Integrative or Integration
Another name for a neurosoma is:
Cell body or soma
The brain and spinal cord are part of the ____________nervous system.
Central
Areas of myelinated fibers in the CNS are called:
White matter
What two boney structures protect the Central Nervous System?
Cranium (part of the skull) and the vertebral column
What tissue layers protect both the brain and spinal cord?
Meninges
What is the other name for the axon of a neuron?
Nerve fiber
What is the “receiving end” of the neuron?
Dendrites
What part of a neuron specializes in sending messages to other cells, such as muscle cells, glands or other neurons?
Axon
What organelle do neurons lack?
Centrioles
Mitochondria are organelles in neurons that specialize in:
Making ATP
At the end of a neuron one would find the:
Axon terminals
Name the branch nervous system that contains nerves that lead to and away from the CNS?
Peripheral Nervous System
What neurotransmitter is used on skeletal muscles?
Acetylcholine
What is found located in the neuron’s nucleus that makes structures such as the kinesins, organelles, neurotransmitters,…?
DNA (genetic plans)
Neurons can undergo mitosis. TRUE or FALSE?
False, they lack centrioles.
Multipolar neurons are named because they have multiple ___________.
Dendrites
Synaptic end bulbs, synaptic knobs and terminal boutons are other names for:
Axon terminals
The nucleus of a neuron is found in the:
neurosoma (cell body or soma)
