Answers

Wilfred
• Two main types will be considered.
• These are exoskeleton and endoskeleton.

1. Exoskeleton
• Exoskeleton is hard outer covering of arthropods made up of mainly chitin.
• Which is secreted by epidermal cells and hardens on secretion.
• It is strengthened by addition of other substances e.g. tannins and proteins to become hard and rigid.
• On the joints such as those in the legs the exoskeleton is thin and flexible to allow for movement.
-Functions of Exoskeleton
• Provide support.
• Attachment of muscles for movement.
• Protection of delicate organs and tissues.
• Prevention of water loss.

2. Endoskeleton:
• It forms an internal body framework.
• This is a type of skeleton characteristic of all vertebrates.
• The endoskeleton is made of cartilage, bone or both.
• It is made up of living tissues and grows steadily as animal grows.
• Muscles are attached on the skeleton.
• The muscles are connected to bones by ligaments.
-Functions
• The functions of endoskeleton include support, protection and movement.
• Locomotion in a finned fish e.g. tilapia.
• Most of the fishes are streamlined and have backward directed fins to reduce resistance due to water.
