Neural Control and Coordination TS

Sympathetic and parasympathetic neural systems are divisions of:

The electrical potential difference across the resting axonal membrane is called as the:

The re-establishment of the resting membrane potential after depolarization is primarily due to:

The change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals is called as:

Consider the two statements:
I. Electric synapses are rare in our system.
II. Impulse transmission across electric synapse is always faster than across a chemical synapse.

What causes the movement of the synaptic vesicles towards the membrane during transmission of impulse across a chemical synapse?

Myelin sheath around the axons in the PNS is secreted by:

A canal called the cerebral aqueduct passes through

Which of the following parts of the human brain functions as a gateway to the cerebrum and is a major coordinating center for sensory and motor signaling?

The brain stem includes all the following except:

The primary commissural region of the brain consisting of white matter tracts that connects the left and right cerebral hemispheres is called as:

The cranial meninge that is in contact with the brain tissue is the:

The human fore-brain does not contain:

Assertion: The resting membrane potential in a neuron is much closer to the equilibrium potential of \( \mathrm{K}^{+} \) ions than it is to equilibrium potential of \( \mathrm{Na}^{+} \) ions.
Reason: While potassium is the principal cation in the intracellular fluid, sodium is the principal cation in the extracellular fluid.

Protein synthesis in neuron is carried out directly by:

Corpus callosum:
