Discovering Human Tissues and Muscles

Some examples of specialized epithelial tissues include ciliated epithelium, which helps move mucus and other substances, and glandular epithelium, which secretes hormones and enzymes. Additionally, stratified squamous epithelium provides protection and is found in the skin and linings of the mouth and esophagus.

Skeletal muscles are attached to bones and allow for voluntary movement. They are striated and have multiple nuclei. Smooth muscles are found in the walls of organs and blood vessels and are responsible for involuntary movements. They are not striated and have a single nucleus. Cardiac muscles are found in the heart and are responsible for the pumping action. They are striated and have a single nucleus.

The primary types of tissues found in the human body are epithelial, connective, muscle, and nervous tissues. Epithelial tissue functions to protect, absorb, and secrete. Connective tissue provides support and connects different body parts. Muscle tissue allows for movement and contraction. Nervous tissue transmits and processes nerve impulses.
