segments of chromosomes that transmit hereditary characteristics
histologist
a medical scientist who specializes in the study of tissues.

The right and left regions of the upper abdomen, beneath the cartilage of the lower ribs; located on either side of the epigastic region
hypogastric region
the middle section of the lower abdomen; beneath the umbilical region
hypoplasia
incomplete or underdeveloped organ or tissue, usually the result of a decrease in the number of cells
inferior
below or downward toward the tail or feet
inguinal region
the right and left regions of the lower section of the abdomen; also call the iliac region
interevertebral disc
a flat, circular, plate-like structure of cartilage that serves as a cushion (a shock absorber) between the vertebrae
lateral
Toward the side of the body, away from the midline of the body
long axis
The long axis of the body; the imaginary line created by directing a vertical line through the middle of the body from the top of the head to a space equidistant between the feet; essentially the midline of the body
lumbar region

lumbar vertebrae
The largest and the strongest of the vertebrae of the spinal column, located in the lower back. The lumbar vertebrae consist of five large segments of the movable part of the spinal column; identified as L1 through L5
lysosomes
Cell organs (or organelles) that contain various types of enzymes that function in intracellular digestion. They destroy bacteria by digesting them.

toward the midline of the body
mediolateral
pertaining to the middle and side of a structure
membrane
a thin layer of tissue that covers a surface, lines a cavity, or divides a space.
midline
the imaginary “line” created when the body is divided into equal right and left halves
midsagittal plane
the plane that divides the body (or a structure) into right and left equal portions.
mitochondria
