Questions and Answers

What are the three types of skeletons mentioned in the text?

exoskeleton, endoskeleton, hydroskeleton

What is the main component of vertebrate skeletons?

bones and cartilages

What is cartilage and where is it found?

Cartilage is a rigid connective tissue found in the skeletal systems of both vertebrates and invertebrates.

What are vertebrates and invertebrates in relation to their skeletons?

Vertebrates have an endoskeleton centered around an axial vertebral column, while invertebrates lack a vertebral column and have a variety of skeletal structures. Signup and view all the answers

Give examples of invertebrate skeletal variations mentioned in the text.

Hard-shelled exoskeletons (arthropods and most molluscs), plated internal shells (e.g. cuttlebones in some cephalopods), rods (e.g. ossicles in echinoderms), hydrostatically supported body cavities (most), and spicules (sponges). Signup and view all the answers

Name and describe the three types of skeletons mentioned in the text?

The three types of skeletons mentioned in the text are exoskeleton, endoskeleton, and hydroskeleton. The exoskeleton is a rigid outer shell that holds up an organism's shape. The endoskeleton is a rigid internal frame to which the organs and soft tissues attach. The hydroskeleton is a flexible internal structure supported by the hydrostatic pressure of body fluids.
