The cerebral cortex is

Mark the correct statement

Electrical synapses are more common in our neural system than chemical synapses
The new potential in post synaptic neuron may be either excitatory or inhibitory
Hypothalamus is the major coordination centre for sensory and motor signaling
The tracts of nerve fibres that connect two cerebral hemispheres are called corpora bigemina

Optic nerve is the –

Saltatory conduction means that the membrane potential changes _______.

Solution

The action potential does not propagate over the length of the myelinated axon but jumps from node of Ranvier to node of Ranvier, skipping the myelinated regions of membrane between the nodes.

Neurons receive signals through their __________ and send signals to other neurons through their __________.

Solution

Dendrites generally receive inputs and conduct signals toward the cell body, whereas axons conduct signals away from the cell body.

Which of the following is the correct direction of travel for a nervous impulse?

Solution

Dendrites collect impulses and carry them toward the nerve cell bodies. Axons then pick up the integrity of the signal and speeds transmission along the axon.
