The skeletal system in vertebrates is divided into the axial skeleton (which consists of the skull, vertebral column, and rib cage), and the appendicular skeleton (which consists of the shoulders, limb bones, the pectoral girdle, and the pelvic girdle).
What are the 5 structures of the skeletal system?
The axial skeleton includes the skull, spinal column, ribs and sternum. The appendicular skeleton includes all upper and lower extremities, the shoulder girdle and the pelvic girdle.
What are the skeletons 5 main functions?
The major functions of the bones are body support, facilitation of movement, protection of internal organs, storage of minerals and fat and haematopoiesis. Together, the muscular system and skeletal system are known as the musculoskeletal system.
What are the main parts of the skeleton?
The skeleton is traditionally divided into two major parts: the axial skeleton and the appendicular skeleton, both of which are pictured in Figure 14.2. 3. The axial skeleton forms the axis of the body. It includes the skull, vertebral column (spine), and rib cage.What is a part of the vertebrate skeleton?
A typical vertebrate skeleton, like this one, includes a cranium, a vertebral column, limbs, and limb girdles where the limbs attach to the main part of the body. The vertebrate endoskeleton may be composed entirely of cartilage or composed of both cartilage and bone.
What are the 6 main parts of the skeletal system?
- The skull protects the brain.
- The vertebrae protect the spinal cord.
- The rib cage, spine, and sternum protect the lungs, heart and major blood vessels.

Freshwater mussel belongs to the family Mollusca which are invertebrates. It contains soft inner body and a rigid outermost shell.

Vertebrates are animals with backbones and skeletal systems. A backbone can also be called a spine, spinal column, or vertebral column. The individual bones that make up a backbone are called vertebrae.
What are the two major divisions of the vertebrate endoskeleton?

What are the types of skeleton?
Types of skeletons. There are two major types of skeletons: solid and fluid. Solid skeletons can be internal, called an endoskeleton, or external, called an exoskeleton, and may be further classified as pliant (elastic/movable) or rigid (hard/non-movable). Fluid skeletons are always internal.
Are teeth bones?
Even though teeth and bones seem very similar, they are actually different. Teeth are not bones. Yes, both are white in color and they do indeed store calcium, but that’s where their similarities end.
Why do bones have joints Class 5?
Ans:- Bones have joints because joint makes up two opposing surfaces that touch each other and allow movement of those two bones.
Are babies born with 300 bones?
A baby’s body has about 300 bones at birth. These eventually fuse (grow together) to form the 206 bones that adults have. Some of a baby’s bones are made entirely of a special material called cartilage (say: KAR-tel-ij). Other bones in a baby are partly made of cartilage.
What connects bone to bone?
A ligament is a fibrous connective tissue that attaches bone to bone, and usually serves to hold structures together and keep them stable.
What is exoskeleton skeleton?
An exoskeleton (from Greek έξω, éxō “outer” and σκελετός, skeletós “skeleton”) is the external skeleton that supports and protects an animal’s body, in contrast to the internal skeleton (endoskeleton) of, for example, a human. In usage, some of the larger kinds of exoskeletons are known as “shells”.

- Hip Exoskeleton. Hips connect the upper limbs and the lower limbs. …
- Knee Exoskeleton. …
- Ankle Exoskeleton. …
- Multiple Joints Exoskeleton.
Do all vertebrates have exoskeletons?
All vertebrates have an endoskeleton. However invertebrates can be divided again between those with an exoskeleton and those with a hydrostatic skeleton. Animals with endoskeletons have skeletons on the inside of their bodies.
What are five examples of vertebrates?
Let’s take a tour of the five main vertebrate groups alive today: the fishes, amphibians, reptiles, birds, and mammals.
