◉ What are the main regions of the human body?
Answer: Axilla, Brachium, Antebrachium, Hand, Head (Cranium),
Neck (Cervical), Thorax, Abdomen, Pelvis, Upper limb, Lower limb,
Back.
◉ What are the five main body cavities?
Answer: 1. Cranial cavity 2. Vertebral canal 3. Thoracic cavity 4.
Abdominal cavity 5. Pelvic cavity.
◉ What does the cranial cavity contain?
Answer: The brain.
◉ What does the vertebral canal contain?
Answer: The spinal cord and spinal nerve origins.
◉ What organs are contained within the thoracic cavity?
Answer: The heart and lungs.
,◉ What are the subdivisions of the thoracic cavity?
Answer: Pleural cavities (each containing a lung) and the
mediastinal cavity (including the pericardial cavity which contains
the heart).
◉ What organs are found in the abdominal cavity?
Answer: Stomach, spleen, liver, gallbladder, small intestine, and most
of the large intestines.
◉ What organs are found in the pelvic cavity?
Answer: Urinary bladder, portions of large intestines, and internal
reproductive organs.
◉ What are the two main patterns used to describe the locations of
abdominal organs?
Answer: Four quadrant pattern and nine region pattern.
◉ What are the midclavicular lines used for in anatomy?
Answer: They are vertical lines through the midpoint of the clavicles
used to delineate regions of the abdomen.
◉ What is the purpose of serous membranes in body cavities?
, Answer: They line body cavities and cover organs, allowing them to
move slightly without friction.
◉ What are the two layers of serous membranes?
Answer: 1. Parietal layer (outer layer lining cavity walls) 2. Visceral
layer (inner layer attached to organ surfaces).
◉ What is the pericardium?
Answer: The serous membrane that lines the mediastinum and
covers the heart and origins of the great vessels.
◉ What is the pleurae?
Answer: The serous membrane that lines the thoracic cavity and
surrounds the lungs.
◉ What is the peritoneum?
Answer: The serous membrane that lines both the abdominal and
pelvic cavities and covers most organs.
◉ What is a cell in the context of human anatomy?
Answer: Cells are the basic structural and functional units of an
organism.
