CH2terms Flashcards
anabolism
process of building up large proteins from small protein pieces called amino acids.
Ana- up / bol to cast / -ism a process
catabolism
process whereby complex nutrients are broken down to simpler substances and energy is released. This process occurs in mitochondria.
Cata- down / bol to cast /
-ism to cast
cell membrane
structure surrounding and protecting the cell. It determines what enters and leaves the cell.
chromosomes
Rod-shaped structures in the nucleus that contain regions of DNA called genes. 46 chromosomes (23 pairs) in every cell except egg and sperm-these only have 23 unpaired.
cytoplasm
all of the material that is outside the nucleus and yet contained with in the cell membrane.
DNA
Chemical found within each chromosome. Arranged like a squence of recipes in code, it directs the activities of the cell.
endoplasmic reticulum
network of canals within the cytoplasm of the cell. Here, large proteins are made from smaller protein pieces.
genes
regions of DNA within each chromosome.
karyotype
Picture (classification) of chromosomes in the nucleus of a cell. The chromosomes are arranged in numerical order to determine their number and structure
metabolism
total of the chemical processes in a cell. It includes catabolism and anabolism. Meta- change/ bol to cast/ -ism a process
mitochondria
Rod-shaped structures in the cytoplasm that provide the principal source of energy(mini “power plants”) for the cell.
nucleus
control center of the cell. It contains chromosomes and directs the activities of the cell.
adipose tissue
collection of fat cells
cartilage
flexible connective tissue often attached to bones and joints. Cartilage forms part of the external ear and the nose. Rings of cartilage surround the trachea
epithelial cells
skin cells that cover the outside of the body and line the internal surfaces of organs.
histologist
specialist in the study of tissues
larynx
voice box; located above the trachea
pharynx
throat. serves as the common passsageway for food (mouth to esophagus) and air (nose to trachea)
pituitary gland
Endocrine gland at the base of the brain.
thyroid gland
endocrine gland that surrounds the trachea in the neck.
trachea
windpipe (tube from throat and larynx to the bronchial tubes.)
ureter
one of two tubes, each leading from a single kidney to the urinary bladder.
urethra
tube from the uriniary bladder to the outside of the body.
uterus
womb; organ that holds the embryo/fetus as it develops
viscera
internal organs in the main cavities of the body, especially the abdomen.
abdominal cavity
space below the chest containing organs such as the liver, stomach, gallbladder, and intestines; also called the abdomen or peritoneal cavity
cranial cavity
space in the head containing the brain and sirrounded by the skull. Cranial means pertaining to the skull
diaphragm
muscle separating the abdominal and thoracic cavities. the diaphragm moves up and down and aids in breathing.
dorsal (posterior)
pertaining to the back

centrally located space outside of and in between the lungs.
pelvic cavity
space below the abdomen containing portions of teh intestines, rectum, urinary bladder, and reproductive organs. Pelvic means pertaining to the pelvis-the hip bones surrounding the pelvic cavity
peritoneum
double-folded membrane surrounding the abdominal cavity. The peritoneum attaches abdominal viscera to muscles and functions as a protective membrane (containing blood vessels and nerves) around the organs.
pleura
double folded membrane surrounding each lung. Pleural means pertaining to the pleura
pleural cavity
space between the pleural layers
spinal cavity
space within the spinal column
thoracic cavity
space in the chest containing the heart, lungs, bronchial tubes, trachea, esophagus, and other organs

vertebrae
Backbones
spinal column
bone tissue surrounding the spinal cavity
spinal cord
nervous tissue within the spinal cavity

lateral
pertaining to the side
medial
pertaining to the middle or near the medial plane of the body
posterior (dorsal)
back surface of the body
prone
lying on the belly (face down, palms down)
proximal
near the point of attachment to the trunk or near the beginning of a structure
sagittal (lateral) plane
lengthwise, vertical plane dividing the body or structure into right and left sides. The midsagittal plane divides the body into right and left halves
superficial
on the surface
superior (cephalic)
above another structure; pertaining to the head
supine
lying on the back, face up palms up
transverse (axial) plane
horizontal (cross sectional) plane dividding the body into upper and lower portions
