2. Tissue is a collection of specialized cells and cell products that perform a specific function. There are four main types of tissue. Can anyone name all four? Great! Nervous, muscular, connective, and epithelia are the four types. Now of the four, we will be focusing on muscular and nervous tissues.

3. Muscle tissue divides into three main groups. Does anyone recall these names? -Makes up the body and muscles. It is voluntary. Skeletal Smooth Cardiac -Widely distributed throughout the body, but mainly in the stomach. It is also involuntary. -Found in the heart and is involuntary.

5. Located in the brain, spinal cord, and nerves. It has neuroglia that provide protection and support. Why is neuroglia referred to as “nerve glue?” Good! It’s because it holds the tissue together.

6. Neurons are also important to the nervous tissue, because they transmit signals. There are three types…. sensory, motor, and interneurons Sensory- send signals from outside the body into the central nervous system Motor- neurons transmit signals to activate muscles and glands Interneurons- send information between sensory neurons and motor neurons.
