The human skeleton is an endoskeleton that consists of 206 bones in the adult. It has five main functions: providing support to the body, storing minerals and lipids, producing blood cells, protecting internal organs, and allowing for movement.
What protects the soft organ of our body?
Bones provide a rigid framework, known as the skeleton, that support and protect the soft organs of the body. The skeleton supports the body against the pull of gravity. The large bones of the lower limbs support the trunk when standing. The skeleton also protects the soft body parts.
How does the skeletal system protect the body’s soft organs?
Your bone contains marrow that produces both red and white blood cells for your body. Organs. Your bones are structured in ways that protect your vital organs. Your skull encases your brain, your ribs protect your heart and lungs, and your backbone covers your spine.
Which part of skeleton protects delicate organs?
For example, the cranium protects the brain, the ribs offer protection to the heart and lungs, the vertebrae protect the spinal cord and the pelvis offers protection to the sensitive reproductive organs.
Does an exoskeleton protect internal organs?
Both hydrostatic and exoskeletons can protect internal organs from harm. Contrast the ways the skeletons perform these functions. Hydrostatic skeletons protect internal organs from harm by cushioning them from external shock. However, these skeletons do not provide protection from external trauma.
Which soft organ is protected by rib cage?
The ribs are connected to the sternum with a strong, somewhat flexible material called cartilage. The rib cage help protects the organs in the chest, such as the heart and lungs, from damage.
Which soft organ is protected by the following skull?
Protection of vital organs, e.g. heart and lungs (protected by rib cage), brain (protected by the skull) (Note: not all vital organs are protected by bones, e.g., the intestines.)
What are the 4 main parts of the skeletal system?
These are (1) the axial, comprising the vertebral column—the spine—and much of the skull, and (2) the appendicular, to which the pelvic (hip) and pectoral (shoulder) girdles and the bones and cartilages of the limbs belong.
What does the skeletal muscle do?
Skeletal muscle – the specialised tissue that is attached to bones and allows movement. Together, skeletal muscles and bones are called the musculoskeletal system (also known as the locomotor system).
How will I protect my internal organs?
Here are seven ways to keep your organs healthy.
- Stay hydrated.
- Eat a balanced diet.
- Exercise consistently.
- Be careful with supplements and over-the-counter medications.

What is protected by the backbone?
The spinal cord is protected by bones, discs, ligaments, and muscles. The spine is made of 33 bones called vertebrae. The spinal cord passes through a hole in the center (called the spinal canal) of each vertebra. Between the vertebrae there are discs that act as cushions, or shock absorbers for the spine.
Which skeleton provides the best protection for the animal?
The hard external skeleton (exoskeleton) not only provides a protective mechanism for many organisms but also assists in movement of insects. The internal skeleton (endoskeleton) present in many animals provides the structural network for support, protection, and movement.
How does a skull protect an animal?
The skull is a bone structure that forms the head in vertebrates. It supports the structures of the face and provides a protective cavity for the brain. The skull is composed of two parts: the cranium and the mandible.

The liver is a large, meaty organ that sits on the right side of the belly. Weighing about 3 pounds, the liver is reddish-brown in color and feels rubbery to the touch. Normally you can’t feel the liver, because it’s protected by the rib cage. The liver has two large sections, called the right and the left lobes.
What is the function of skull?
The function of the skull is both structurally supportive and protective. The skull will harden and fuse through development to protect its inner contents: the cerebrum, cerebellum, brainstem, and orbits.

How many bones are we born with?
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).
What are the 206 bones called?
The adult human skeleton usually consists of 206 named bones. These bones can be grouped in two divisions: axial skeleton and appendicular skeleton.

By this definition, the masseter or jaw muscle is the strongest. The 1992 Guinness Book of Records records the achievement of a bite strength of 4,337 N (975 lbf) for 2 seconds.
Which is the longest muscle in our body?
Abstract. The sartorius muscle is the longest muscle in the human body. It is strap-like, up to 600 mm in length, and contains five to seven neurovascular compartments, each with a neuromuscular endplate zone. Some of its fibers terminate intrafascicularly, whereas others may run the full length of the muscle.
What type of bone is the ribs?
In vertebrate anatomy, ribs (Latin: costae) are the long curved bones which form the rib cage, part of the axial skeleton. In most tetrapods, ribs surround the chest, enabling the lungs to expand and thus facilitate breathing by expanding the chest cavity.
What is the name of the thick bone cage that protects our brain?
The brain is housed inside of a bony covering called the cranium. The cranium protects the brain from injury and along with the bones that protect the face are called the skull. Between the skull and brain is the meninges, which consist of three layers of tissue that cover and protect the brain and spinal cord.

Are soft bodied animals with shells inside or outside their bodies called exoskeleton?
An exoskeleton is a hard outer layer that protects an animal’s soft insides. Insects, spiders, and crustaceans have exoskeletons. Soft-bodied animals called mollusks are the second largest group of invertebrates. Octopuses, jellyfish, sponges, and starfish are a few of the many mollusks that live in or near the water.
Where is the exoskeleton located?
An exoskeleton is the rigid covering found on the exterior of many animals, particularly invertebrates such as arthropods and mollusks. Much like the internal endoskeleton of vertebrates, the exoskeleton is responsible for supporting the structure of an animal’s body.
