QuestionAnswer
where are striated muscles located heart and skeletal muscles
the pressure in the systemic arteries during ventricular contraction is systolic blood pressure
difference between the systolic and diastolic pressure of the expanding and contracting arterial walls is the pulse
input from what system causes vasoconstriction during exercise and therefore an increase in blood pressure sympathetic nervous system
cardiac muscle is striated involuntary
in what order does the impulse for depolarization travel through the heart SA node, AV node, bundle of his, purkinje fibers
the wave on the ecg/ekg that is associated with the atrial wall depolarization P wave
SA node is located in the wall of which chamber Right Atrium
the muscular sphincter located between the stomach and duodenum is the pylorus
type of cell responsible for the transmission of impulses through the nervous system Neuron
system anatomically composed of the brain and spinal cord central nervous system
functions that an animal does not have to consciously control, such as peristalsis in the intestines, are influenced by the autonomic nervous system
cranial nerves and spinal nerves are anatomically part of what system peripheral nervous system
sensory nerves are considered afferent nerves
an imbalance of what minerals can affect nerve function Na and K
when stimulus is strong enough to cause complete depolarization, it has reached threshold
what happens within the neuron that allows local anesthetics to be effective sodium channels being blocked
smooth muscles can be found in stomach
which muscle cells have single nuclei smooth and cardiac
cattle and swine display what type of estrous cycle polyestrous
dogs demonstrate what type of estrous cycle diestrous
what species is an induced ovulator cat/feline/queen
in what stage of estrous cycle does corpus luteum develop metestrus
hormone produced by a developing ovarian follicle estrogen
what hormone contracts the female reproductive tract to help move spermatozoa into the oviducts oxytocin
to achieve normal pregnancy, blastocyst attaches to what structure endometrium
giving birth is known as parturition
from the estrous cycle to parturition, in what order are following hormones released estrogen, progesterone, oxytocin
animal with cotyledonary placenta sheep
in cotyledonary placentation the mothers side of the attachment is called the caruncle
a pregnant mare has what kind of placentation diffuse
a pregnant bitch has what kind of placentation zonary
a pregnant rodent has what kind of placentation discoid
a pregnant queen has what kind of placentation zonary
the canine uterus is shaped like the letter Y
how many mammary glands are typically found on a bitch 8-12
which reaction is the result of parasympathetic nervous system stimulation decreased heart rate
result of sympathetic nervous system stimulation dilated pupils
acetylcholine is released as a neurotransmitter by postganglionic parasympathetic nerve fibers
neurotransmitter that is most responsible for "fight or flight" reaction epinephrine
in a healthy heart, the heartbeat is initiated by the SA node
on an ecg/ekg the T Wave is most closely associated with ventricular repolarization
on an ecg/ekg the P Wave is most closely associated with atrial depolarization
which of the following conditions is most life threatening ventricular fibrillation
increasing a neuron's permeability to Na will cause hyper excitability
