makeup exam 1Online version beginning exam by Manda Nunez 1 Motor neurons a are large, have long axons, and stimulate muscles. b make up a majority of neurons in the brain and have tiny axons, that analyze input from one set of neurons and communicate with others. c have various shapes that best respond to specific environmental stimuli, such as light, odor, or touch. d 2 Sensory neurons a on the axon terminal of the presynaptic neuron b have various shapes that best respond to specific environmental stimuli, such as light, odor, or touch c make up a majority of neurons in the brain and have tiny axons, that analyze input from one set of neurons and communicate with others. d 3 Presynaptic membrane a on the dendrite or cell body of the postsynaptic neuron b the gap that separates the membranes c on the axon terminal of the presynaptic neuron. when an action potential occurs it fuses with the membrane and releases there contents into the synaptic cleft. they bind into receptors than an action can occur as a result. d 4 Postsynaptic membrane a The part of a neuron or cell that receives neurotransmitters from the presynaptic neuron and responds, often by opening ion channels. b on the axon terminal of the presynaptic neuron c the gap that separates the membranes d 5 Synaptic cleft a on the axon terminal of the presynaptic neuron b the gap that separates the membranes c d 6 Neurotransmitter receptors a in the postsynaptic membrane are specialized proteins that react to neurotransmitter molecules. b on the axon terminal of the presynaptic neuron. when an action potential occurs it fuses with the membrane and releases there contents into the synaptic cleft. they bind into receptors than an action can occur as a result. c The part of a neuron or cell that receives neurotransmitters from the presynaptic neuron and responds, often by opening ion channels. d 7 Neural plasticity a orm the myelin sheaths in the brain and spinal cord. produce proteins that are important for strong neurons. NF, lGFl, these proteins help grow and form synapses as well as supporting existing neurons b refers to the continual remodeling of neuronal connections c Glial cells in the peripheral nervous system that form the myelin sheath around axons, increasing the speed of nerve signal transmission. d 8 Oligodendrocytes a form the myelin sheaths in the brain and spinal cord. produce proteins that are important for strong neurons. NF, lGFl, these proteins help grow and form synapses as well as supporting existing neurons b Glial cells in the peripheral nervous system that form the myelin sheath around axons, increasing the speed of nerve signal transmission. c gaps between sections of myelin where the axon is exposed d 9 Schwann cells a gaps between sections of myelin where the axon is exposed b Glial cells in the peripheral nervous system that form the myelin sheath around axons, increasing the speed of nerve signal transmission. c star-shaped cells with many processes that stretch around and between neurons and, sometimes, blood vessels; secrete chemicals; help form the outer membrane around the brain 10 Nodes of Ranvier a star-shaped cells with many processes that stretch around and between neurons and, sometimes, blood vessels; secrete chemicals; help form the outer membrane around the brain b gaps between sections of myelin where the axon is exposed c tiny, mobile cells that remove debris from injured or dead cells d 11 Astrocytes a star-shaped cells with many processes that stretch around and between neurons and, sometimes, blood vessels; secrete chemicals; help form the outer membrane around the brain b convey information from the body CNS (afferent neurons) c tiny, mobile cells that remove debris from injured or dead cells d 12 Microglial cells a Glial cells in the peripheral nervous system that form the myelin sheath around axons, increasing the speed of nerve signal transmission. b tiny, mobile cells that remove debris from injured or dead cells c form the myelin sheaths in the brain and spinal cord. produce proteins that are important for strong neurons. NF, lGFl, these proteins help grow and form synapses as well as supporting existing neurons d 13 Sensory nerves a convey information from the body CNS (afferent neurons) b transmit information from the spinal cord and brain - muscles and glands. (efferent neurons) c tiny, mobile cells that remove debris from injured or dead cells d 14 Motor nerves a gaps between sections of myelin where the axon is exposed b transmit information from the spinal cord and brain - muscles and glands. (efferent neurons) c star-shaped cells with many processes that stretch around and between neurons and, sometimes, blood vessels; secrete chemicals; help form the outer membrane around the brain d 15 Ionictropic Receptor a Glial cells in the peripheral nervous system that form the myelin sheath around axons, increasing the speed of nerve signal transmission. b A receptor protein that forms part of a ligand-gated ion channel, so that binding of ligand (e.g. a hormone or neurotransmitter) to the receptor causes opening of the channel, permitting ions to flow through it. c star-shaped cells with many processes that stretch around and between neurons and, sometimes, blood vessels; secrete chemicals; help form the outer membrane around the brain d 16 Metabotropic receptors a G proteins influence the ion channels but it can also effect enzymes and accurate second messengers b form the myelin sheaths in the brain and spinal cord. produce proteins that are important for strong neurons. NF, lGFl, these proteins help grow and form synapses as well as supporting existing neurons c star-shaped cells with many processes that stretch around and between neurons and, sometimes, blood vessels; secrete chemicals; help form the outer membrane around the brain d
