Terms Pertaining to the body as a whole Flashcards
anabolism
process of building up large proteins from small protein pieces called amino acids. Ana- means up, bol means to cast, and -ism is a process
catabolism
process whereby complex nutrients are broken down to simpler substances and energy is released. Cata- means down, bol means to cast, and -ism is a process
cell membrane
structure surrounding and protecting the cell. It determines what enters and leaves the cell
chromosome
rod-shaped structures in the nucleus that contain regions of DNA called genes. There are 46 chromosomes (23 pairs) in every cell except for the egg and sperm cells, which contain only 23 individual, unpaired chromosomes
cytoplasm
all the materials that is outside the nucleus and yet contained within the cell membrane.
DNA
chemical found within each chromosome. Arranged like a sequence of recipes in code, it directs the activities of the cell
endoplasmic reticulum
network of canals within the cytoplasm of the cell. Large proteins are made from smaller protein peices
genes
regions of DNA within each chromosomes
karyotype
picture of chromosomes in the nucleus of the cell. The chromosomes are arranged in the numerical order to determine their number and structure
metabolism
total of the chemical processes in a cell. It includes catabolism and anabolism. Meta- means change, bol means to cast, and -ism means a process

away from the surface
distal
far from the point of attachment to the trunk or far from the beginning of a structure
frontal (coronal) plane
vertical plane dividing the body or structure into anterior and posterior portions
