neurons

receive, process, and transmit information.

Glial cells

support, protect, nourish, and insulate neurons.

soma

the neurons control and maintenance center. -contains the nucleus and most organelles -produce proteins -provides energy -keeps the neurons alive.

dendrites

Receive information from other neurons. Detects information

axon

carries information away from the soma.

synapse

The specialized junction where one neuron communcates with another cell.

nucleus

Contains DNA and controls cell activity.

Rough ER

Produces protein, called nissl bodie in neurons.

free ribsomes

Produce proteins used inside the neurons

smooth ER

produce lipids , store calcium, and perform other chemical functions.

Golgi apparatus

modifies, sort and pack proteins.

mitochondria

Produce ATP through aerobic cellular respiration.

neuronal membrane

seprates the neuron's inside from its outside asnd controls movement of substances.

cytoskeleton

-gives the neurons its shape -support the neuron -help distribute organelles -provides pathways form transporting materials.

microtubules

made from tubulin transport tracking running throught the neuron.

microfilaments

made from actin help the neuron change shape and move.

neurofilaments

made form strong protein strands provide structural strenth the "bones" of the cytoskelton.

hint***

Microtubules=track microfilamanets=movement neurofilments=bones

lesson :

The axon has no rought ER and very frew little ribsomes, so most materialas must be produced in the soma and transported through the axon.
