Nervous System and Neurons

A neuron has three basic parts: dendrites (which receive signals), cell body or cyton (which contains the nucleus and processes signals), and axon (which transmits signals). Axon is clearly one of these three fundamental components. Myelin is a protective sheath around axons, pons is a brain region, and dura mater is a protective membrane - none are basic neuron parts.

The myelin sheath is a fatty layer that wraps around axons, providing electrical insulation and protection. Nodes of Ranvier are gaps in the myelin sheath, synapses are junctions between neurons, and axon terminals transmit signals to other cells - none of these insulate and protect the axon.

A relay neuron (interneuron) connects sensory neurons to motor neurons, processing and transmitting information in reflex arcs and neural pathways. Dendrites receive signals, axons transmit them, and cyton is the cell body - none of these directly pass information from sensory to motor neurons.

The cell body (also called cyton or soma) contains the nucleus and most of the cell's organelles. Dendrites and axons are extensions from the cell body, and nodes of Ranvier are gaps in the myelin sheath - none of these contain the nucleus.

This option is correct. Ependymin protects from strokes and neural regeneration.

Muscle weakness in LEMS is caused by auto-antibodies to voltage gated calcium channels at the presynaptic side of the neuromuscular junction.

The cells of this tissue are called nerve cells or neurons.

The brain, spinal cord and nerves are all composed of the nervous tissue. The cells of this tissue are called nerve cells or neurons. Many nerve fibres bound together by the connective tissue make up a nerve.

There are 31 pairs of spinal nerves in the human body, categorized by the region of the spine they emerge from (cervical, thoracic, lumbar, sacral, and coccygeal).

The autonomic nervous system is responsible for regulating involuntary bodily functions, such as heart rate and digestion, which are essential for maintaining homeostasis. The central and peripheral systems are broader categories that include both voluntary and involuntary control.

A synapse is the junction between two neurons where nerve impulses are transmitted via neurotransmitters. The other terms are not biological structures for neural communication.

The medial lemniscus carries sensory information from the gracile and cuneate nuclei to the thalamus. It is part of the posterior column-medial lemniscus system, which transmits touch, vibration sense as well as the pathway for proprioception.

A tissue which is specialized to transmit messages in our body is nervous tissue. Brain, spinal cord, and nerves are all composed of nerves tissue. Nervous tissue contains highly specialised unit cells called nerve cells. Nerve cells have the ability to receive stimuli from within or outside the body and conduct to different parts of the body. the impulses travels from one nerve cells to another nerve cell
