Different types of muscle contractions: Isometric- muscle contraction without a change in the length of muscle Concentric- Muscle applies force as it shortens (lifting) Eccentric- Muscle applies force as it lengthens (lowering) Difference between type 1 and type 2 muscle fibers * Slow-twitch fibers * Type-I fibers * Fatigue resistant * Contract slowly and with relatively little force * Rely primarily on oxidative energy system * Fast-twitch fibers

The first and foremost of the surprise is the vast reservoir of chemical factories‚ inside the tiny body. Though this creature does not have a vertebral column‚ a proper demarcation of body and head‚ and not even a brain‚ yet this Jellyfish is seen to possess numerous different chemicals‚ some of which are extremely toxic and poisonous too.

forefeet (awkward gait) due to the enlarged calves. Between the ages 11 and 13 the young man will often develop skeletal deformities. The back muscles become weak‚ and the spine starts to curve. The spine is a column of small bones called vertebrae. There are five sections of the vertebral column. The body’s weight falls on the lumbar vertebrae. This excessive curvature bends toward the front causing the body to lean forward. This condition is known as Lordosis. In addition‚ lateral curvature of

portion of the nervous system‚ the CNS coordinates the body’s interaction with the environment. The CNS is contained within the dorsal cavity‚ with the brain in the cranial subcavity (the skull)‚ and the spinal cord in the spinal cavity (within the vertebral column). Then human nervous system is the most complex object know to science‚ as it includes the intricate CNS and a brain with 10 billion neurons and many times more interneural connections (Anissimov 2007). For some people‚ this brain and the increase
