Intro to ANAPHY (LEC) Flashcards
Field in the biological sciences concerned with the identification & description of the
body structures of living things.
Anatomy
Studies structures that can only be seen with the aid of
microscope
Microscopic anatomy
Studies structures that can be seen by the naked eye
Gross anatomy
Studies surface markings of the body to understand internal anatomy
through visualization and palpation. Gives us an idea of what is inside our body because
we can’t directly see some organs because they are greatly covered by layers of fats,
muscles, and our skin.
Surface anatomy
Studies structures of specific body systems.
Systemic anatomy
- Studies structures found within specific regions of the body
Regional anatomy
Studies changes (Gross to Microscopic) in organs or tissues associated with the disease process. Focuses with the changes in the appearance of the organ. Can be studied through biopsy.
Pathological anatomy
Studies structures that can be viewed with x-ray, MRI, and CT
scans.
Radiographic anatomy
Studies the development of the first 8 weeks of development after
fertilization of the human egg. First 8 weeks of life is important because that is when
the fetus is developing majority of the organs
Embryology
Studies the complete development of an individual from
fertilization to death. studying humans from the day of the fertilization of the egg until the human will die.
Developmental Biology
Field in the biological sciences concerned with the functions of the structures (cells,
tissues, and organs).
Physiology
- Studies the function of the heart and blood vessels
Cardiovascular Physiology
Studies the function of the lungs and air passageways.
Respiratory Physiology
Studies functional changes associated with the disease and aging
Pathophysiology
Studies the function of the kidneys
Renal Physiology
Studies the function of nerves.
Neurophysiology
Study of body’s defense against invading microorganism. Studies how the
body would defend itself.
Immunology
Study of hormones.
Endocrinology
Organization in Human Body (from smallest to biggest)
Cells -> Tissues -> Organs -> Systems
Group of cells and extracellular matrix that work together to perform a
particular function. Fibers and ground substances make up extracellular matrix.
Tissue Level
Atoms and Molecules; smallest unit of matter that can participate in
chemical reactions. Atoms and molecules can combine together to form the cells.
Molecules will combine together to form cells and cells are the smallest structural and
functional unit of the human body
Chemical Level
Molecules combine to form cells. Cells are basic Structural and
functional unit of an organism; smallest living unit in the body.
Cellular Level
Group of related organs with common function.
System Level
Group of two or more tissues functioning together
Organ Level
Digestive + Integumentary + Skeletal + Cardiovascular +
Respiratory + Reproductive + Muscular + Nervous + Urinary + Endocrine +
Lymphatic System
Organism Level
Levels of Structural Organization and Body
Systems
Atom -> Molecule -> Macromolecule -> Organelle -> Cell -> Tissue -> Organ -> Organ
System -> Organism
Characteristics of the Living Organism?
Metabolism, Responsiveness, movement, Growth,, Differentiation, Reproduction
Any process that living things use to actively maintain fairly stable conditions necessary
for survival. Balance.
Homeostasis
cycle of events in which the status of a body condition is
monitored, evaluated, changed, remonitored, reevaluated and so on.
Feedback Systems
monitors changes in controlled condition and
sends input to the control center
Receptor/Sensor
sets range of values within which a
controlled condition should be maintained
Control center
receives output from the control center and produces a
response or effect that changes controlled condition
Effector
Reverses the change in the controlled condition.
Negative Feedback system
tends to strengthen or reinforce a change in one body’s
controlled conditions.
Positive Feedback system
Anatomical position
Stand erect facing the observer Head level Eyes facing directly forward Feet flat on floor and directed forwards Upper limbs at the sides with palms facing forward
- if the body is facing down
Prone position
if the body is facing up
Supine position
Parts of Head
skull, face
Neck function
supports head and attach to trunk
Parts of Trunk
Chest, abdomen, pelvis, upper limbs
- the lower most portion of the trunk.
Where we can find the male and female internal
genitalia
[pelvis
where we can find the stomach, the
small and the large intestine
Abdomen
where we can find our heart and lungs
Chest -
