BSC 2085L A&P Lab Midterm Review( Complete Solution Rated A)
Be able to identify in which body cavity a major organ or body part would be
found. (Heart,
... [Show More] lungs, kidneys, ovaries, stomach, intestines)
Dorsal Body Cavity
Consists of the cranial and spinal cavities.
Cranial cavity – within the rigid skull, contains the brain
Spinal cavity – runs within the bony vertebral column, protects the
spinal cord
Spinal cord is a continuation of the brain, the cavities containing them
are continuous with each other
Ventral Body Cavity
Thoracic cavity – separated from the rest of the ventral cavity by the
muscular diaphragm. Contains heart and lungs which are protected by the
bony rib cage
Subdivided into the lateral pleural cavities – each surround a lung,
and the medial mediastinum.
The mediastinum contains the pericardial cavity – encloses the
heart, and it also surrounds the remaining thoracic organs (esophagus,
trachea, and others)
Abdominopelvic cavity – cavity inferior to the diaphragm
Superior abdominal cavity – area that houses the stomach,
intestines, liver, and other organs
Inferior pelvic cavity – partially enclosed by the bony pelvis and
contains the reproductive organs, bladder, and rectum. Tips away from
abdominal cavity in a posterior direction
Umbilical region - centermost region, belly button
Epigastric region – immediately superior to the umbilical region,
overlies most of stomach
Hypogastric (pubic) region – inferior to umbilical region
Iliac regions – lateral to the hypogastric region and overlying
superior parts of hip bones
Lumbar region – between the ribs and the flaring portions of the hip
bones, lateral to umbilical region
Hypochondriac region – flanking epigastric region laterally and
overlying lower ribs
4. Know what muscle separates the thoracic from abdominal cavity.
Diaphragm
5. On a dissected rat be able to identify: lungs, heart, liver, stomach, spleen, large
intestine, and diaphragm.
Lab 2 Tissues and Skin: Exercises 5-6:
1. Characteristics and function of epithelia.
Epithelial tissues cover surfaces. Epithelia cover the external body surface (the
epidermis), line its cavities, and generally mark off our “insides” from our
outsides.
Glands are classed as epithelia because they almost always develop from
epithelial membranes
Functions include protection, absorption, filtration, excretion, secretion, and
sometimes sensory reception
Characteristics –cells fit closely together to form membranes, or sheets of cells,
that are bound together by specialized junctions [Show Less]
