Ribsosomes - Tiny, spherical structures composed of protein and RNA. They provide a structural
support and enzymatic activity to link amino acids to synthesize proteins.
Rough ER - Studded with ribosomes.
Proteins synthesized on ribosomes then move through the tubules of the endoplasmic reticulum, where
they fold into their characteristic 3D shapes, and then go to another organelle, the Golgi apparatus, for
further processing.
Give an example of homeostasis - In the body, if there is a stimulus (like your body temperature
rising above a set point), receptors (in this case, thermoreceptors) send signals to the control center (or
hypothalamus), the control center then then detects the deviation from the set point and signals
effector organs, these effectors go into effect (skin blood vessels dilate, sweat glands secrete). The
response to the stimulus (body heat being lost to its surrounds and temperature dropping to normal) is
the body going back to its set point. <- example of negative feedback
What is anatomy and physiology? - Anatomy is the study of the structure of an organism, whereas
physiology is the study of the functions an organism performs. Ex. The skeleton of a frog vs. what the
skeleton does in relation to the frog's functions
What is homeostasis? - Homeostasis is the maintenance of a stable internal environment.
Name the body systems - Integumentary (skin), Muscular System, Skeletal System, Nervous
System (nerves/neurons), Endocrine Systems (glands that secrete hormones), Circulatory System
(Blood), Lymphatic System, Respiratory System, Digestive System, Urinary System, Reproductive System
(the only system that is not needed for life, just to preserve the species)
What is negative and positive feedback? - Negative and positive feedback are homeostatic control
mechanisms
, What is negative feedback? - Negative feedback prevent sudden, severe changes in the body,
corrects the set point, causes opposite of bodily disruption to occur, i.e. the 'negative'. Ex. Body
temperature, blood pressure & glucose regulation.
What is positive feedback? - Positive feedback increases/accelerates the action body, short lived -
does not require continuous adjustments. Ex. Blood clotting and child birth
toward the head end of the body; upper - superior/cranial (example, the hand is part of the
superior extremity).
away from the head; lower - inferior/caudal (example, the foot is part of the inferior extremity).
Front - Anterior or ventral (the knee is located on the anterior of the leg)
What makes up the 2 sides of DNA and which 2 bases complement each other? - A binds to T, G
binds to C
Back - posterior/dorsal (ex. the shoulder blades are located on the dorsal side of the body)
toward the middle of the body - medial (example, the middle toe is located on the medial side of
the foot).
toward or nearest the trunk or the point of origin of a part - Proximal (example, the proximal end
of the femur joins with the pelvic bone).
away from or farthest from the trunk or the point or the origin of a part - Distal
beyond the surface - Deep
on the surface - superficial
