Midterm 1 Flashcards
What is the relationship between anatomy and physiology?
Both rely on each other. Form (anatomy) determines function (physiology).
What is anatomy?
The study of the physical structure, morphology, or form of organisms or their parts.
Anatomical terms are used to indicate: ___ and ___
Direction and location
One word that defines anatomy?
Form
What is physiology?
The branch of biology concerned with the way in which organisms, systems, organs, cells, organelles, and bio-molecules carry out their chemical or physical functions.
One word defining physiology?
Function
What are the four fields of anatomy?
- Gross anatomy
- Microscopic anatomy
- Developmental anatomy
- Applied anatomy
Two fields of Gross Anatomy?
- Systemically : organ systems
- Regionally : look at area where something happens
Two fields of Microscopic Anatomy?
- Cytology: study of cells
- Histology: study of tissues
What is Developmental Anatomy?
The development from fertilization to maturity
What is Applied Anatomy?
The structure and function
Is Anatomy static or dynamic?
Static
Is Physiology static or dynamic?
Dynamic
Define Biochemistry.
The branch of science concerned with the structure characteristics, properties, and actions of the molecules involved in all of the chemical and physiochemical processes occurring within living organisms.
True or False: It’s argued that biochemistry is essentially anatomy and physiology at the molecular level
True
What is the smallest unit to carry out chemical reactions?
Molecules
Situated in front of or in the front of another part
Anterior
Pertaining to the head or anterior portion of the body
Cranial
Situated or occurring near the oral or nasal region
Rostral
Situated behind or toward the rear or behind another part
Posterior
Pertaining to the tail or posterior portion of the body
Caudal
Toward the belly
Ventral
Toward the back surface of the body
Dorsal
Pertaining to the middle; closer to the median plane or to the midline of the body or structure
Medial
Denoting a position farther from the median plane or midline of the body or of a structure
Lateral
List the organization of living organisms.
Molecules —> Organelles —> Cells —> Tissues —> Organs —> Organ Systems —> Organisms
What is a molecule?
Two or more atoms linked together, and the smallest unit to carry out chemical reactions
What is an organelle?
Specialized parts that make up cells
What is a cell?
Basic unit of life
What are tissues?
Group of cells similarly anatomically with specific functions
What are organs?
Group of two or more tissues that work together and carry out specific functions
What is an organ system?
Integration of different organs to carry out major functions
List the 4 tissues organs are made up of:
- Nervous
- Muscle
- Connective
- Epithelial
List the 11 organ systems:
- Integumentary
- Circulatory
- Digestive
- Endocrine
- Excretory
- Immune
- Muscular

What two organ systems does the pancreas use?
Endocrine and Digestive
What 2 organ systems does the heart use?
Cardiovascular and Muscular
What happens if one system does not do their job?
Other organ systems could not function properly or at all, and could lead to death.
What are the primary organs of the Integumentary System?
Skin and its derivatives (hair, feathers, nails)
What are the primary organs of the Muscular System?
Striated/Voluntary/Skeletal muscle (meat); Smooth/Visceral muscle; Cardiac muscle (tendons)
What is striated muscle?
Voluntary neural input
What is cardiac muscle?
Involuntary neural input, and only located in the heart
What are the primary organs of the Skeletal System?
Bones, cartilage, and ligaments
Primary organs of the Digestive System:
Esophagus, stomach, small intestine, and large intestine
Differences between ruminants and monogastrics:
Ruminants:
-have symbiotic relationship with microbes
-have volatile fatty acids to help balance energy
Monogastrics:
-do not have relationship with microbes
-use glucose to balance energy
Primary organs of the Cardiovascular System:
Heart, arteries, arterioles, capillaries, venules, and veins
Primary organs of the Respiratory System:
Larynx, trachea, syrinx, primary bronchi, and lungs
What other primary organ do avians (birds) have that mammals do not?
Air sacs
How many air sacs do avians have?
7 or 9
Primary organs of the Excretory System:
Kidneys and ureters
What waste do mammals excrete out, and how much energy is required for this?
Urea and needs higher levels of water to excrete; does not need a lot of energy
