Question

ARE THE BASIC FUNCTIONAL UNITS OF THE NERVOUS SYSTEM THE PART OF THE NEURON RESPONSIBLE FOR INTEGRATING INCOMING SIGNA AND HOUSING THE NUCLEUS IS CALLED THE NEURON CELL BODIES FOUND IN CLUSTERS IN THE CNS ARE CALLED COLLECTIONS OF NEURON CELL BODIES FOUND IN THE PNS ARE CALLED NEURON FIBERS RUNNING THROUGH THE CNS FORM BUNDLES CALLED NEURON FIBERS RUNNING THROUGH THE PNS FORM BUNDLES CALLED THE CYTOPLASM OF THE NEURON IS CALLED ARE THE CYTOSKELETAL ELEMENTS OF THE NEURON WHAT TYPE OF ORGANELLES ARE NISSL BODIES DENDRITES ARE NEUROTRANSMITTERS RELEASED BY OTHER NEURONS GIVE ANOTHER NAME FOR AXONS WHAT IS THE FUNCTION OF AXONS THE ELECTRICAL CURRENT PRODUCED TRAVELS ACROSS THE CELL BODY, AND IF IT IS GREAT ENOUGH, IT ELICITS A REGENERATIVE ELECTRICAL SIGNAL CALLED AN THEY BEAR RECEPTORS FOR OR , THAT TRAVELS DOWN THE AXON THE AXON OF MOTOR NEURONS BEGINS JUST DISTAL TO A SLIGHTLY ENLARG CELL BODY STRUCTURE CALLED THE THE POINT AT WHICH THE AXON HILLOCK NARROWS TO AXON DIAMETER IS REFERRED TO AS THE THE AXON ENDS IN MANY SMALL STRUCTURES CALLED OR WHICH FORM SYNAPSES OR JUNCTIONS WITH NEUROINS OR EFFECTOR CELLS (GIVE EITHER THE AXON ENDS IN MANY SMALL STRUCTURES CALLED AXON TERMINALS, OR SYNAPTIC KNOBS, WHICH FORM OR EFFECTOR CELLS EACH AXON TERMINAL IS SEPERATED FROM THE CELL BODY OR DENDRITES OF THE NEXT POSTSYNAPTIC NEURON BY A TINY GAP CALLED THE WHAT DO SYNAPTIC VESICLES CONTAIN OR JUNCTIONS WITH NEURONS

Explanation / Answer

NEURONS are the basic functional units of the nervous system.

The part of the neuron responsible for integrating incoming signals and housing the nucleus is called the - CELL BODY.

Neuron cell bodies found in clusters in the CNS are called - NUCLEI.

Collections of neuron cell bodies found in the PNS are called - GANGLIA.

Neuron fibers running through the CNS form bundles called - TRACTS.

Neuron fibers running through the PNS form bundles called - NERVES

The cytoplasm of the neuron is called - NEUROPLASM

NEUROFIBRILS are the cytoskeletal elements of the neuron

What type of organelles are Nissl bodies - ROUGH ENDOPLASMIC RETICULUM

Dendrites are RECEPTIVE REGIONS, they bear receptors for neurotransmitters released by other neurons

Give another name for axons - NERVE FIBERS

What is the function of axons - to CONDUCT REGION OF NEURON AND GENERATE IMPULSE

The electrical current produced travels across the cell body, and if it is great enough, it elicits a regenerative electrical signal called an ACTION POTENTIAL or IMPULSE, that travels down the axon ( give either )

The axon of motor neurons begins just distal to a slightly enlarged cell body structure called the - AXON HILLOCK

The point at which the axon hillock narrows to axon diameter is referred to as the - INITIAL SEGMENT

The axon ends in many small structures called AXON TERMINALS, or TERMINAL BOUTONS, which form synapses or junctions with neurons or effector cells ( give either )

The axon ends in many small structures called axon terminals, or synaptic knobs, which form SYNAPSES or junctions with neurons or effector cells

Each axon terminal is seperated from the cell body or dendrites of the next postsynaptic neuron by a tiny gap called the - SYNAPTIC CLEFT

What do synaptic vesicles contain - NEUROTRANSMITTER.
