Nervous Tissue

The central nervous system consists of

• spinal cord and spinal nerves

• cranial and spinal nerves

• brain and cranial nerves

• brain and spinal cord

• spinal cord and cranial nerves

Neurons that convey information to the CNS from the receptors located in various parts of the body are described as

• central

• motor

• afferent

• efferent

The two control systems of the body that regulate homeostasis are the

• nervous and muscular

• nervous and skeletal

• nervous and skeletomuscular

• nervous and endocrine

• endocrine and muscular

The autonomic nervous system does not send impulses to

• skeletal muscle

• cardiac muscle

• smooth muscle

• glands

• smooth muscles in the walls of blood vessels

The sympathetic and parasympathetic nervous systems are subdivisions of which nervous system?

• central

• autonomic

• somatic

• cranial

• sacral

The cell responsible for myelin production on the CNS is the

• astrocyte

• oligodendrocyte

• microglial cell

• Schwann cell/neurolemmocyte

• ependymal cell

Synaptic end bulbs are found in

• dendrites

• axons

• muscle cell membrane

• neuroglia

• neurolemmocytes

Synaptic vesicles contain

• sodium ions

• potassium ions

• chloride ions

• neurotransmitters

The myelin sheath covering most axons functions to

• conserve energy in the form of heat

• protect against microbial attack

• increase the speed of impulse conduction

• slow down the speed of impulse conduction

• to provide a friction-free environment

The part(s) of the neuron that receive(s) impulses from another cell is (are)

• dendrites

• axons

• the neurolemma

• Node of Ranvier

• nucleus
