35 Association tracts connect the lobes of the same cerebral

35. Association tracts connect the lobes of the same cerebral hemisphere 36, when a neuron is resting, its membrane potential is zero 37. The corpus callosum is an example of a commissural tract of the cerebrum 38. The afferent nervous system consists ofall outgoing motor pathways. 39. If a skeletal muscle moved, it would be responding to stimulus from the somatic nervous system. 40. Absolute refractory period is the time when a neuron will not send a nerve impulse no matter how strong the stimulus is.

Solution

Answer 35) true.

A nerve tract, is a bundle of nerve fiber connecting nuclei of the central nervous system. There are three main kinds of white matter tracts: projection, commissural, and association.

Association tracts connect different regions within the same hemisphere of the brain. Long association fibers connect different lobes of a hemisphere to each other, whereas short association fibers connect different gyri within a single lobe.

Answer 36) false.

The resting membrane potential of a neuron is about -70 millivolt- this means that the inside of the neuron is 70 mV less than the outside.

Answer 37) true

corpus collosum is a form of commissural tract that connects the right and left hemispheres.

It is the largest white matter structure of the brain

Answer 38) false

It consists of incoming sensory pathway.

Efferent nervous system consist of outgoing motor pathway.

Answer 39) true.

Skeletal muscle respond to the somatic nervous system.

It is associated with the voluntary control of body movements via skeletal muscles. The Somatic nervous system consists of sensory nerves, and motor nerves

answer 40) true.

It is the time during which another stimulus given to the neuron will not lead to a second action potential. It is because Na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.It coincides with nearly the entire duration of the action potential.
