Questions and Answers
What are the functions of the skeleton?
The functions of the skeleton include serving as a support or framework for the body, providing a surface for muscle attachment, supplying calcium to the blood, and being an important site for the formation of blood cells.
What are the two types of skeleton?
The two types of skeleton are the exoskeleton and the endoskeleton.
What is the exoskeleton of vertebrates composed of?
The exoskeleton of vertebrates consists of hardened bony or horny structures that develop in the skin and provide external protection to the animal.

Study Notes
Musculoskeletal System
- The skeleton is an essential part of the body in every vertebrate animal, providing several functions.
Functions of the Skeleton
- Serves as support or framework for the softer parts of the body.
- Provides a firm surface for the attachment of muscles used in movement and locomotion.
- Supplies calcium to the blood.
- Important site in the formation of blood cells.
Types of Skeleton
- Exoskeleton: consists of hardened bony or horny structures that develop in the skin, providing external protection to the animal.
- Endoskeleton: consists almost entirely of bone and cartilage.
Skeletal System of Frogs/Toads
- The skeleton of frogs/toads is almost entirely endoskeletal in nature.
- Exoskeleton is poorly developed in frogs/toads.
Muscles and Skeleton
- Skeletal muscles and skeleton are considered together as a functional unit that permit body movements and locomotion.
- Muscles are attached to the bones by a connective tissue called tendon.
