What is Locomotion? What are cartilages?
please answer in very short definations.
Answers
Answer:
Animal locomotion, in ethology, is any of a variety of methods that animals use to move from one place to another. Some modes of locomotion are self-propelled, e.g., running, swimming, jumping, flying, hopping, soaring and gliding.
Cartilage is a tough but flexible tissue that is the main type of connective tissue in the body. Around 65–80% of cartilage is water, although that decreases in older people, and the rest is a gel-like substance called the 'matrix' that gives it its form and function.

About locomotor
The locomotor system is also known as the musculoskeletal system. It is made up of the skeleton, the skeletal muscles, tendons, ligaments, joints, cartilage and other connective tissue. These parts work together to allow movement.
The brain controls the movements of the body, using information from:
the eyes
the ears, including special canals which give us a three-dimensional sense of motion
the muscles themselves, called ‘muscle sense’ or kinaesthesia.
The skeleton
The skeleton is made up of 206 bones. Bones are a form of connective tissue reinforced with calcium and bone cells. Bones have a softer centre, called marrow, where blood cells are made. The three main functions of the skeleton are:
support – the body is supported and shaped by the skeleton – for example upright posture would be impossible without a spine
protection – our internal organs are protected by our skeleton, such as the brain inside the skull, the heart and lungs inside the ribcage
movement – most skeletal muscles are attached to bones in opposite working groups, like the biceps and triceps muscles of the upper arm.
The skeleton also stores minerals (such as calcium) and lipids (fats), and produces blood cells in the bone marrow.
