1. When a neuron is at rest, the neuron maintains an electrical polarization(i.e., a negative electrical potential exists inside the neuron's membrane with respect to the outside). This difference in electrical potential or voltage is known as the resting potential. At rest, this potential is around -70mV.
The statement true about neurons is c) No two neurons in the nervous system have the same appearance.
The most important organelle in the cell body is the nucleus. The nucleus contains the cell's DNA and regulates all processes in the cell. The cell needs DNA to act as a blueprint to direct cellular activity. The nucleus also contains the nucleolus, which makes ribosomes needed for protein production.
NeuronsThus, the correct answer is the option (C), 'Neurons'.
All neurons have at least one dendrite but one or more axons. Neurons have one axon, and one or more axons. Motor neurons usually have a more complex structure than sensory neurons. Motor neurons are multipolar neurons, which are more complex than unipolar and bipolar neurons, which are sensory.
Both neurons and neuroglia are important cells in the nervous system.
The cell body, also called the soma, is the spherical part of the neuron that contains the nucleus and holds all of the general parts of the cell. The cell body connects to the dendrites, which bring information to the neuron, and the axon, which sends information to other neurons.
Nucleus-contains genetic material (chromosomes) including information for cell development and synthesis of proteins necessary for cell maintenance and survival. You just studied 9 terms!
the cell body of a neuron. contains the nucleus, and provides the life processes of the entire cell.
The basic unit of the nervous system is a nerve cell, or neuron.
Neurons. Neurons are the cells considered to be the basis of nervous tissue. They are responsible for the electrical signals that communicate information about sensations, and that produce movements in response to those stimuli, along with inducing thought processes within the brain.
Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning.
