smooth and skeletal muscles. The skeletal muscles are the muscles that can be controlled voluntarily‚ in things such walking and picking things up. The skeletal muscles are made up of bundles of muscle fibres (which are also known as myofibrils‚ as can be seen below). Each of the muscle fibres contain many sarcomeres‚ which is the most basic form of striated muscle tissue- they consist of two long proteins which slide against each other in order to make the muscles move. These two proteins are

1. White matter is found on the outside or surface of the cord. It connects the cord and the brain and is made up of nerve fibres. White matter contains motor fibres which run down from the motor centre of the brain‚ the cerebrum and the cerebellum to the motor cells of the cord Sensory fibres also run up the cord from the sensory cells of the cord to the sensory centre of the brain. 2.

actin. These filaments slide past each other to produce a contraction which changes both the length and shape of the cell. The primary function of the muscle is to produce both movement and force. Skeletal muscle is composed of bundles of muscle fibres containing myofibrils of thick and thin filaments (myosin and actin). Skeletal muscle have distinct striations due to the overlapping of the myosin and actin held in place by the sarcolemma. Skeletal muscles cover majority of the skeleton‚ giving

uses acetylcholine. The cell bodies of the parasympathetic nervous system are located in the spinal cord (sacral region) and in the medulla. In the medulla‚ the cranial nerves III‚ VII‚ IX and X form the preganglionic parasympathetic fibres. The preganglionic fibre from the medulla or spinal cord projects to ganglia very close to the target organ and makes a synapse. This synapse uses the neurotransmitter called acetylcholine. From this ganglion‚ the post-ganglionic neuron projects to the target

SILK Silk is undisputedly the most beautiful of all natural fibers‚ with its unearthly sheen. It is also uncommonly strong‚ even at its finest‚ when it is almost invisible. It is unlike any other fiber used to make fabrics‚ for it is neither grown in a field or on an animal. It is not manufactured in a factory. A humble caterpillar about the size of a woman’s smallest finger produces the silk fiber‚ spinning it out of its mouth‚ using tiny fore-legs to place the silk where it should go. It is
