Chapter 1
Pgs 19-20

2. Body Regions Axial Head Neck Trunk/Torso Appendicular
Thorax :upper portion (superior)
Abdomen: midportion
Pelvis: lower portion (inferior)
Appendicular
Pectoral girdle & upper limbs
Pelvic girdle & lower limbs

4. Body Cavities
Spaces within the body which house the internal organs (viscera).
Consists of two main cavities:
Dorsal cavity-the cavity along the back, posterior side of the body
Ventral cavity-the cavity along the front, anterior side of the body

5. Subdivisions of Body Cavities
Two major cavities within the axial portion:
Dorsal Cavity
Towards Back
Cranial cavity (head)
Spinal/vertebral cavity (neck, thorax, abdomen)
Ventral Cavity
Towards Front
Orbital cavities (head)
Nasal cavities (head)
Oral cavities (head)
Otic Cavities (head)
Thoracic cavity (thorax)
Pericardial cavity
Pleural cavities
Abdominopelvic cavity (abdomen & pelvis)
Abdominal cavity
Pelvic cavity

7. Sheets of tissue that serve to protect body structures.
Body Membranes
Sheets of tissue that serve to protect body structures.
Serous Membranes
Double layered sheets of connective tissue separated by a small amount of fluid
Parietal layer-outer layer, forms the outer boundary of the cavity
Visceral layer-inner layer, sits directly on the organ it covers
Serous fluid-secreted from the membrane to separate the parietal & visceral layers.

9. Body Membranes cont. Peritoneal Membranes
Covers the stomach, liver, spleen, gallbladder, small & large intestine in the abdominal cavity.
Covers the distal end of the large intestine, bladder & internal reproductive organs in the pelvic cavity.

Body Systems consist of a collection of organs that work together to perform a specific task or function.
