TEAS - A&P Quiz Questions
which immune cells are derived from stem cells?
T cells, B cells, and eisonophils - more specifically derived from multipotent hemopoietic stem cells
what is biologically happening at a Z line?
a network of proteins serves as a point of anchorage for actin (thin filaments)
what may follow the T wave and what does it represent?
a small U wave that is further repolarization of the ventricles
what does the heart rhythm ultimately lead to?
atrial depolarization
what is the posterior area of the brain connected to the spinal cord called?
brain stem
what are the 4 parts of the stomach?
cardiac, fundus, body, pylorus
what kind of immunity are T-cells involved in?
cell-mediated immunity
what enzyme begins the breakdown of acetylcholine?
cholinesterase
which plane runs vertically through the body perpendicular to the midline and divides the body into front and back (anterior and posterior) sections?
coronal (or frontal)
what does the P wave represent on the ECG?
depolarization of the atria
what enzyme begins the breakdown of fats?
lingual lipase
what are the secondary functions of the respiratory system?
pH regulation of blood, thermoregulation, odor detection, and the production of speech
what enzyme begins the breakdown of proteins into amino acids
pepsin
what are the three parts of the brain stem?
pons, midbrain, medulla oblongata
which plane runs parallel to the midline of the body and divides the body into right and left sections?
sagittal
which enzyme begins the digestions of polysaccharides into simpler sugars?
salivary amylase
where does the heart rhythm start?
sinoatrial node
what follows the P wave of the ECG and what does it represent?
the QRS interval, which represents depolarization of the ventricle
what follows the QRS interval of the ECG and what does it represent?
the ST segment and the T wave, which corresponds to the repolarization of the ventricle
what are sarcomeres separated by?
the Z line
what are the three phases of the ovarian cycle?
the follicular phase, ovulation, and luteal phase
what are the characteristics of the body of the stomach?
the largest, most central region - it curves toward the right to form a J shape
what is the fundus region of the stomach?
the most superior region of the stomach
what region of the stomach does the body funnel into?
the pylorus
how many major waves are seen on the ECG of a heartbeat?
three major waves
where do T-cells complete their development?
thymus
where do T-cells mature?
thymus
which plane divides the body into imaginary upper (superior) or lower (inferior) halves?
transverse
is the proliferative phase part of the ovarian or the uterine cycle?
uterine cycle
when does the initial activation of T-cells occur?
when they encounter their specific antigen on the surface of an antigen-presenting cell? (APC)
what happens in the cardiac region of the stomach?
where food is emptied into the stomach
which of the following is produced in the mucosal lining to aid in immune defense?
while all answers are part of the immune defense, only IgA is produced in the mucosal lining
The human body can be divided into how many primary body planes?
3; sagittal, coronal, transverse
how many parts can the stomach be divided into?
4
which of the following is not part of the brain stem? A. midbrain B. Pons C. Hypothalamus D. Medulla Oblongata
C. Hypothalamus - the other three parts listed in the question are the three major parts of the brain stem
which of the following is NOT a secondary function of the respiratory system? A. pH regulation of the blood B. thermoregulation C. speech production D. heart rate regulation
D. Heart rate regulation - this is controlled by the autonomous nervous system and doesn't have much to do with the respiratory system
