Answer:

motor Nerves.

Explanation:

These are bundles of axon of the spinal cord located in the CNS. They originated at the motor cortex of the brain.

They conduct response signals out of the CNS through the spinal cord to reach the effector(muscles).These signals pass through the brain stem and the spinal cord ipsillaterially, to emerge at the ventral side of the spinal cord to terminate at the skeletal muscles or the smooth muscles.

The bundles of AXON are called FASICICLES

They are bundle of axons which transduce signals from the CNS to peripheral neurons of the muscles of the body.They are different from the motor neuron which have their cell bodies in the spinal cord and dendrites at the terminal ends.

However, they communicated with the muscles they innervated through the motor neuron at the terminal.

They have high concentration of neurotransmitter acetylcholine vesicles for chemical transmission at synapse, and calcium ion in the presynaptic motor nerves for migration of the vesicles for increasing the size of end-plate potential

Hormones are _____.

serious [3.7K]

Answer:

The correct is B Hormones are chemical signals between cells transported in blood or hemolymph.

Explanation:

Hormones are called chemical messenger of the cell because they transmit chemical information from one cell to the target cell and regulating the functioning of that target cell by activating specific proteins related to the functioning of that target cell.

Hormone is secreted from its source gland such as Pituitarygland, thyroid gland,adrenal gland.After being secreted hormones are transported via the blood stream to the target cell and binds to receptor of that target cell thus allowing the target cell to exert its biological function.

Liula [17]

The illustration is a representation of the different ways molecules are transported across a cell membrane, that represents active transport is IV.
Active Transport is described as a process that involves the movement of molecules against a gradient or an obstruction from a location of lower concentration to a region of greater concentration.
A protein pump uses ATP, which is a form of stored energy, to move molecules during active transport.The process of active transport, which moves molecules using ATP as an external energy source.
Some examples of active transport include the absorption of glucose in the human intestine and the uptake of minerals or ions into the root hair cells of plants.
Active transportation comes in two flavors:

Primary active transport
Secondary active transport.
