The fibrous connective tissue makes up ligaments which attach bones and joints together and tendons which attaches muscles and bones together. The nervous tissue is the tissue that senses stimuli and then transmits the signal from one part of the animal to another. The neuron is the functional unit of the nervous tissue or the nerve cell which is specialized in transmitting signals called nerve impulses. This consist of the cell body and two or more extensions that are called dendrites and axons. The dendrites transmit an impulse that is sent towards the cell body, and the axons transmit impulses away from the cell body.
Muscle tissue is made up of long, excitable cells that are capable of considerable contraction.
These are arranged in a parallel pattern within the cytoplasm of the muscle cells. There are a large number of microfilaments that are made of contractile proteins actin and myosin. Since this is needed for movement it is one of the most abundant tissues in most animals. The vertebrate body there are three types of muscle tissue. The first is skeletal muscle, which is normally responsible for the voluntary movement in the body.
