Cells

Covers internal and external surfaces in order to form boundaries between different environments, and forms glands. Also makes up the interior lining of the digestive tract and outer layer of skin. 80% of all cancers develop from epithelial tissues bc of the high regeneration rate

Supports, binds, protects other tissues together. Most abundant and distributed tissues in the body

Forms the brain, spinal cord and nerves. Nerve cells have the ability to generate electric signals and use those signals to communicate with each other to become aware of the world outside and inside, to store this information as memory, and o use it to make conscious decisions

Ability to contract and cause movement by converting chemical energy from our food into mechanical energy.

Cannot be controlled voluntarily. found mostly in walls of hollow organs, such as bladder and stomach. Smooth muscle cells help us to empty our bladder

Found in wall of the heart only. cannot be controlled by us and can generate its own contraction rhythm. cardiac muscle cells pump blood through the circulation

Needs signals from the nervous system to contract. skeletal muscles attach to bones or skin and help body to move and manipulate its environment. skeletal muscle cells help us move our bodies around

If neoplasm does not cause damage to the surrounding structures and does not spread (metastasize) to other locations

Neoplasms that grow locally destructive and spread to other areas of the body and causing death if untreated

Grow locally destructive but no not spread. may cause death if untreated but can be cured by surgical removal or radiation treatment

Most common form of skin cancer. is semi-malignant and will not spread but grow locally invasive

Rarest form of skin cancer and also deadliest as it spreads early and forms metastases that are resistant to chemotherapy

Any tumor regardless of cause

Localized accumulation of blood in the tissue

Malignant tumor arising from muscle tissue
