Anatomy Flashcards
what is the simplest of all living things?
Cell
what are the three main cell parts
plasma membrane, nucleus and cytoplasm
what is abnormal and uncontrolled cell growth but dont result in illness or death
benign tumors
What is malignant tumors?
true cancers, and can cause serious illness or even death.
Which cells can divide and multiply at the expense of normal, healthy cells.
malignant tumors
What are cancers that have the tendency to send forth cells into distant sites of body?
metastasis
what are body of cells organized to perform a certain function?
tissue
what are the four different types of tissue?
epithelial tissue, connective, muscle, and nerve tissue
What kind of tissue is the inner and outer surfaces of the body? such as skin
epithelial tissue
What kind of tissue connects or supports other body structures?
connective tissue
What kind of tissue relaxes and contracts to allow body parts to move and certain organs to function?
muscle tissue
what kind of tissue extends throughout the body to carry messages to and from brain?
nerves tissue
What type of tissue covers organs, lines body cavities and forms portions of some ducts and glands
epithelilal tissue
what type of epithelial cells from the outer layer of skin, serves much more than a cosmetic role? if these didn’t form a barrier; the bacteria would penetrate skin and invade
squamous cells
What type of epithelial cells line the digestive tract, stomach, and intestines, are column-like shape
columnar epithelial cells
what type of epithelilal cells form a kind of tissue that secretes its products directly into bloodstream.
endocrine gland cells
what type of epithelial cells from tissue that protects kidney tubules and covers the ovaries and certain glands?
cuboidal cells
What type of cells can be soft and rubbery or hard and rigid depending on the job it has?
connective tissue
what are type of connective tissues?
fascia, cartilage, adipose tissue, blood, and lymph
what are the three types of muscle tissues?
voluntary, involuntary, and cardiac
what does nerve tissue make up?
brain, spinal cord and nerves
what are protective covers on the brain and spinal cord
meninges
is the outer boundary of the cell and is made up of proteins and lipids
plasma membrane
what is the thing that is strong enough to keep the cell intact, yet thin enough to let substances in and out
plasma membrane
What are the substances that are allowed into the cell membrane?
food and oxygen
what items do the cell membranes let out?
waste products
What is in the middle of the cell and commands and controls the center
nucleus
