A substance synthesized at the cell body must undergo ______ transport to reach the synaptic knobs.
cricket20 [7]

The cell body must undergo Anterograde transport to reach the synaptic knobs.

The synaptic feature is to transmit nerve impulses between two nerve cell neurons or among a neuron and muscle cellular. Synapses connect one neuron to every other and are thus liable for the transmission of messages from the nerves to the mind and vice versa.

Synapses are a part of the circuit that connects sensory organs, like those who come across aches or touch, within the peripheral frightened gadget to the mind. Synapses connect neurons inside the mind to neurons inside the rest of the frame and from those neurons to the muscle tissues.

Synaptic transmission is the method at synapses by way of which a chemical sign is launched from one neuron and diffuses to other neurons or goal cells where it generates a sign which excites, inhibits, or modulates mobile hobby.

What are the differences between the endocrine and nervous systems?
son4ous [18]

Answer:

Explanation:

The endocrine system is a complex of glands that secrete <u>hormones</u> as a chemical messenger. These hormones carry information and instructions throughout the bloodstream from one part of the body to another. These hormones control many body functions such as respiration, sensory perception, metabolisms, growth, reproduction, the mood among others.

On the other hand, the nervous system is made up of neurons that communicate with each other to extend a message (from our own body or the outside) to the brain, for analysis and further decision of what to do with that information. A group of neurons, sensory neurons, respond to several stimuli such as touch, light, and sound to let the brain know about the surrounding environment. Another group of neurons, motor neurons, work inside the body and carry signals to active muscle or glands.
