cuts body into front & back (anterior and posterior)
cuts at the midline into right and left sides

cranial & spinal
The ventral body cavity includes which 2 cavities?
thoracic & abdomino-pelvic
In the abdomino-pelvic region, the top center region is called...
the epigastric region.
In the abdomino-pelvic region, the most-middle region is called...
the umbilical region.
In the abdomino-pelvic region, the bottom middle region is called...
the hypogastric region.
In the abdomino-pelvic region, the top right and left sections are called...
the hypochondriac regions.
In the abdomino-pelvic region, the middle left and right regions are called...
the lumbar regions.
In the abdomino-pelvic region, the bottom right and left regions are called...
the iliac regions.
- composed of RNA and protein
- sites of protein synthesis
- can be free-floating or attached to the rough ER
Rough Endoplasmic Reticulum (2 major points)
- studded with ribosomes
- area for storage and transport of the proteins made on the ribosomes
- the external face synthesizes phospholipids and cholesterol
Smooth Endoplasmic Reticulum (3 points)
- site of steroid and lipid synthesis
- lipid metabolism
- drug detoxification
- packages proteins to be exported
- packages phospholipids to be incorporated into the plasma membrane
- packages lysozymes for intracellular use
contain oxidase enzymes that detoxify alcohol, hydrogen peroxide, and other harmful chemicals
- inner membrane has folds known as cristae
- produce ATP
- paired, cylindrical shapes that lie perpendicular to each other.
- direct the formation of the mitotic spindle during cell division
the cell carries out its normal metabolic activities
- the spindle forms
- each chromosome will duplicate, held together at the centromere
- the chromosomes will line up at the equator of the spindle
- this imaginary line is called the metaphase plate
- the chromosomes will split from each other
- the microtubules will pull the chromosomes to their respective sides
- new nuclear envelope develops around the chromatin
- the spindle breaks down and disappears
- chromosomes resume their chromatin form
- does not include the division of the plasma membrane, which happens in cytokinesis
