SPS411: REVISION 2 (NERVOUS SYSTEM)

The spinal cord is an organ in the

• nervous system.

• lymphatic system.

• endocrine system.

• respiratory system.

Which part of a neuron contains the nucleus?

• Axon

• Cell body

• Dendrite

• Synaptic end bulb

The central nervous system consists of the

• cranial and spinal nerves.

• somatic and autonomic divisions.

• brain and spinal cord.

• sympathetic and autonomic divisions.

The branch of a neuron that carries a nerve impulse away from the cell body is the

• axon.

• dendrite.

• node of Ranvier.

• soma.

The Nodes of Ranvier are

• gaps in the myelin sheath.

• sites of neurotransmitter storage.

• where the nucleus of a neuron is located.

• sites of myelin production.

The part of the nervous system that transmits impulses from CNS to skeletal muscle is the

• somatic nervous system.

• central nervous system.

• autonomic nervous system.

• afferent division.

Which of these effectors is not directly controlled by the autonomic nervous system?

• Smooth muscle

• Cardiac muscle

• Skeletal muscle

• Most glands

What is the division that conveys impulses to the central nervous system?

• Motor

• Efferent

• Somatic

• Afferent

The glial cells are

• transmit electrical signals.

• support, protect and nourish the neurons.

• located in CNS.

• short/long nerve fiber.

Which of the following is the BEST describe the motor neuron?

• Carry impulse from receptor to central nervous system.

• Carry impulse from central nervous system to effectors.

• Mainly connected to special sense.

• Usually unipolar in structure.
