Answer:
B. Synapse
Explanation:
The synapse is the space or the communication between two neurons or betwenn a neuron and a muscular cell or a secretory cell. Humans use the chemical synapse. The processes begings with an action potential producing a depolarization openening neurotransmitters (NT) vesicles releaseing calcium allowing the NT allowing the NT to the membrane of the postsynaptic cell sending the signal.
A synapse is the site of communication between two neurons or a neuron and another effector cell, with the synaptic cleft being the gap where neurotransmitters are released and signal transmission occurs.
Explanation:The site of communication between two neurons or between a neuron and another effector cell is called a synapse. The synapse includes a narrow space known as the synaptic cleft, which is the actual gap between the presynaptic neuron's terminal button and the postsynaptic neuron's dendrite, axon, or soma. During neurotransmission, neurotransmitters are released from synaptic vesicles within the axon terminal of the presynaptic neuron.
These neurotransmitters cross the synaptic cleft and bind to receptors on the postsynaptic cell, thereby transmitting the signal. If the postsynaptic cell is another neuron, the binding of neurotransmitters can initiate an action potential, continuing the signal transmission process.
A male patient presents with the following respiratory volumes and capacities: TV = 500 mL, ERV-600 mL, IRV 2,700 mL.
What is this patient's VC? Are these values normal? If not, are they more consistent with an obstructive or restrictive disease pattern? Explain.
Answer:
The patient VC is 3800ml.
Explanation:
Vital capacity may be defined as the maximum amount of air that a person can expel after maximum inspiration. Tidal volume is the sum of expiratory reserve volume, inspiratory reserve volume and tidal volume.
Vital capacity (VC) of a patient is 3800 (500+600+2700). The patients has restrictive disease pattern because its expiratory reserve volume has been decreased. The patients suffers from the lung restriction and respiratory failure.
Thus, the patient VC is 3800 ml and has restrictive disease pattern.
The patient's Vital Capacity, calculated as the sum of Tidal Volume, Expiratory Reserve Volume, and Inspiratory Reserve Volume, is 3,800 mL, lower than the average for males, and may suggest a restrictive lung disease.
Explanation:The patient's Vital Capacity (VC) can be calculated by adding the Tidal Volume (TV), the Expiratory Reserve Volume (ERV), and the Inspiratory Reserve Volume (IRV) together. In this case, the VC will be the sum of 500 mL (TV) + 600 mL (ERV) + 2,700 mL (IRV), which equals 3,800 mL.
The average male VC is approximately 4,800 mL, so this patient's VC is somewhat lower than usual. These values might suggest a restrictive disease pattern, characteristic of conditions such as pulmonary fibrosis or muscular dystrophy, in which lung expansion is limited and the total lung volume is reduced.
