Nerve Tissue Made up by nerve cells called………………………………….. Neuron is the only cell capable of…………………………………………… a mpulse Neuron has main three parts: ………………………………………………………………………………….., and dendrites. Axons and dendrites are ……………………………………………. of the cell. Neurons highly …………………………………………………and have lost the ability to reproduc e. Neuroglia support and protect ………………………….. Do not transmit impulses. There are 10 x more neuroglia cells than neurons. Types of neurons based on function: Motor neurons - these carry a message to a muscle, gland, or other effector. The y are said to be efferent, i.e. they carry the message……………………………the central nervous system. Sensory neurons - these carry a message in ……………………………………………. They are afferent , i.e. going towardthe brain or spinal cord. Interneuron ( association neuron, connecting neuron) - these neurons …………………………………… neuron with another. Interneurons connect the sensory neurons with the motor neurons. Types of neurons based on structure: Mltipolar neuron- has many ………………. or……………………, the dendrites and the axon. Ex: motor neuronsBipolar neurons –with ……………… processes, a dendrite and an axon Unipolar neurons - which have only ………….. process, classified as an axon. Unipolar neurons are found as most of the body's sensory neurons. Their dendrites are the exposed branches connected to ………………………, the axon carries the action potential from………………… in to the central nervous system.
