Anatomy Flashcards
Histology is the study of
Tissues
The plasma membrane separates the
intracellular fluid inside cells from the extracellular fluid outside.
all body cells are surrounded by a selectively permeable
plasma membrane
Acromial area is
the tip of the shoulder
Axillary area is
armpit
The dorsal body cavity has two subdivisions which are
Cranial cavity and vertebral cavity
Both the brain and the spinal cord are covered by membranes called Both the brain and the spinal cord are covered by membranes called
meninges.
The more anterior and larger of the closed body cavities is the
ventral body cavity
The ventral body cavity has two subdivisions which are
thoracic and abdominopelvic cavity
The ventral body cavity houses internal organs collectively called the
viscera or visceral organs
The medial cavity of the thorax containing the heart, great vessels, thymus, and parts of the trachea, bronchi, and esophagus is the
mediastinum
The thoracic cavity is further subdivided into lateral _____ cavities (ploo´ral), each enveloping a lung, and the medial _____
pleural and mediastinum
A _______occurs when part of the stomach slides through the diaphragm into the thoracic cavity, allowing stomach acid to cause heartburn (which is actually irritation of the esophagus, not the heart)
hiatal hernia
The walls of the ventral body cavity and the outer surfaces of the organs it contains are covered by a thin, double-layered membrane, the _______ it is the moist membrane found in closed ventral body cavities.
serosa or serous membrane
The part of the membrane lining the cavity walls is called the
parietal serosa (pah-ri´ĕ-tal; parie = wall)
The part of the double-layered membrane that lines the outer surfaces of organs within the ventral body cavity.
Visceral serosa
the ___ serosa is never exposed but is always fused to the cavity wall.
parietal
the serous membranes are separated not by air but by a thin layer of lubricating fluid, called
serous fluid
barely present, slitlike ____ is filled with serous fluid.
serous cavity
The ____of an object is equal to the actual amount of matter in the object, and it remains constant wherever the object is.
Mass
is defined as the capacity to do work, or to put matter into motion
energy
The energy of motion or movement, e.g., the constant movement of atoms, or the push given to a swinging door that sets it into motion.
Kinetic Energy
Stored or inactive energy.
Potential Energy
Energy stored in the bonds of chemical substances.
Chemical energy
