Nerve Tissue

Question 1

Definition of neurons

Answer 1

The primary responsibility of these neurons is to transmit nerve impulses from the sensory organs to the central nervous system (cns) and from the cns to the effector organs

Question 2

Three types of neurons

Answer 2

Sensory neurons
Interneuron
Motor neuron

Question 3

Function of a motor neuron

Answer 3

Conduct nerves impulses from the cns to the effector organs to bring out a response

Question 4

Function of a sensory neuron

Answer 4

Conduct nerve impulses from the sensory organs to the cns so that the stimulus is interpreted and action can be taken if necessary

Question 5

Function of interneuron

Answer 5

Connect neurons together
Form a connection between the motor neuron and sensory neuron in the cns.

Question 6

Differentiate between motor neuron and sensory neuron

Answer 6

Motor neuron
-dendrites are short
-has many dendrites
-cell body occurs closer to the end of the neuron
-dendrites do not have myelin sneath and neurilemma sneath

Sensory neuron
-dendrite is long
-has one dendrite
-cell body occurs in the middle of the neuron
-dendrite has myelin sneath and neurilemma sneath
