Chapter 6 Flashcards
What is cell division
Mitosis
What is protoplasm
A substance in which cells of all living thing are composed. Colorless, jelly like substance where food elements such as proteins, fats, carbohydrates, mineral salts, and water are present
What is an organelle?
Tiny organs floating in cell. Has the mitochondria and endoplasmic reticulum which allows the other organelles to move and provides protein for the skin
Nucleus
Active protoplasm found in center of cell
Nucleoplasm
Within the nucleus of the cell. A fluid that contains protein and DNA
Cytoplasm
All the protoplasm of a cell except that found in the nucleus. It contains the food material necessary for cell growth, reproduction and self repair
Cell membrane
Part of the cell that encloses the protoplasm and permits soluble substances to enter and leave
Mitosis
Cell division, happens when the cell divides into 2 daughter cells. Body doesn’t grow if cell doesn’t divide
Cell metabolism
Chemical process that takes place in living organisms. Cells are nourished and carry out their activities
Anabolism
Is constructive metabolism. The process of building up larger molecules from smaller ones
Catabolism
Phase of metabolism when complex compounds within the cells are broken down into smaller ones
Tissue
Collection of similar cells that perform a particular function
Connective tissue
Supports, protects and binds together other tissues of the body
Adipose tissue (fat)
Gives smoothness and contour to the body. Collagen and elastin in the connective tissue
Mitochondria
Heart and lungs of cells. Beginning of skin. Speaks to cells that make the skin and stimulates the fibroblast(makes collagen and elastin which gives shape and form to skin
Interstitial fluid
Blood plasma found in spaces between tissue cells. It carries waste and impurities away from cells.
4 different tissue
Connective and adipose (bone, cartilage, fat
Epithelial (skin)
Muscle
Nerve
Glycosaminoglycans (GAGS)
Gel like fluid that surrounds the collagen and elastin to keep it healthy. It is apart of the senovial fluid( lubricant for joints)
Polysaccrites
Sugars, hydrators
Fibroblast
Cells that manufacture collagen and elastin
How many bones in human head
22
Cranium 8
Face 14
Bones of cranium
Occipital bone - hindmost bone of the skull
2 parietal bones- form sides and crown(top) of cranium
Frontal - forms the forehead
2 Temporal- forms sides of head in the ear region
Ethmoid - light, spongy bone between the eye sockets that forms part of the nasal cavities
Sphenoid- joints all the bones of the cranium together
Bones of the face
2 nasal bones form bridge of nose
2 lacrimal bones, the smallest, fragile bone at front inside part of eye socket
2 zygomatic bones, Malta or cheek bones
2 maxillary bones form upper jaw
Mandible forms the lower jawbone, largest and strongest bone on face
2 turbinal(turbinate), thin layers of spongy bone on either of the outer walls of the nasal depression
Vomer- is a flat, thin bone that forms part of the nasal septum
2 palatine bones- form the hard palate of the mouth
Neck bones
Hyoid - U shaped bone at base of the tongue that supports the tongue and its muscles
Cervical vertebrae - the 2 bones of the top part of the vertebral column in the neck region
