Answer:
Y is probably excitatory and Z is probably inhibitory
Explanation:
- Two neurons communicate with each other generally by releasing neurotransmitters.
- The neuron which releases the neurotransmitter is termed as presynaptic neuron and the neuron to which the neurotransmitter binds to exert its effects is called as postsynaptic neuron.
- Based on the nature of the neurotransmitter released, the presynaptic neurons can either be inhibitory or excitatory in nature.
- The change in the membrane potential of the postsynaptic neurons depends on the total sum of inputs coming from different pre synaptic neurons at a given time.
- From the given situation, the stimulation by X alone is causing deploarization of 0.5 mV which shows that it is causing excitation, and since depolarization is increasing when X and Y are stimulaneously stimulated Y is also excitatory in nature. However the depolarisation is not occurring when X and Z are stimualted together and hence, Z is probably inhibitory in nature.
Answer:
A nurse observes a few small, yellow nodules on the cervix of a client during the speculum exam. They are not painful or odorous, and a thin, clear discharge is present. The nurse recognizes that these are most indicative of nabothian cysts.
Explanation:
Nabothian cysts or nabothian follicles are also called mucinous retention cysts or epithelial cysts. It is a mucus-filled cyst on the surface of the cervix. Many women have multiple cysts they are common, benign and considered a normal feature of the adult cervix. They may be translucent or opaque, whitish to yellow, and range from a few millimeters to 3 to 4 cm in diameter. They are most often caused when stratified squamous epithelium of the ectocervix which is the nearest portion to the vagina that grows over the simple columnar epithelium of the endocervix which is the nearest portion to the uterus.
There are no serious complications or threat to your health with nabothian cysts.
The answer is: 'constrict the blood vessels in their large ears to reduce transfer of external heat to the blood in their ears.' This is an example of thermoregulation. Thermoregulation is the ability of the<span> </span>body to keep body temperature<span> within certain boundaries, even when the temperature of the surrounding environment is very different. The regulation of temperature by thermoregulating organisms is one aspect of </span>homeostasis. By using heat exchange systems, such as employed in this example, the animal will need to expend less energy on behavioural adaptations to maintain a constant body temperature.
