binds structures together and provides support and protection

Main feature of muscle tissue
contactile, voluntary and involuntary movements. accomplished by the interaction of contractile proteins.
Types of muscle tissue
Cardiac: branching cells connected by discs
skeletal muscle: long striated cells w multiple nuclei
smooth muscle: no striations
what is Nervous tissue and what is it made up of

made up of neurons that collect, process and transmit information around the body via electronic signals.
where is nervous tissue
