Question

Q.3 Distinguish between the following pairs in one or two sentences each (a) Axon and dendrites (b)Tendons and ligaments

Answer 1

Answer:

Hello,

Explanation:

a)

Axon

• It is single and very long (several metres) and of uniform diameter  

• Carries nerve impulse away from the cell body to the next neuron

• Single per neuron

• Transmits neuron signals  

• May be myelinated or non- myelinated

• Nissl's granules absent

Dendrites  

• They are short (under 1.5mm), heavily branched and tapering

• Carries nerve impulses from synapses towards the cell body

• Usually many per neuron

• Receives neuron signals

• Always non- myelinated

• Nissl's granules present

b)

→Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.

→A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.
