Summary Introduction

Introduction :

Breathing is controlled from regions of the brainstem respiratory centers, which control both inspiration and expiration. These areas initiate and regulate nerve impulses that travel to various muscles of breathing.

Expert Solution & Answer

Answer to Problem 1PL

Correct answer :

The correct answer is option (d) Pineal gland.

Explanation of Solution

Explanation/justification for the correct answer :

Option (d) Pineal gland.Pineal gland is a small conical endocrine gland that arises from the roof of the third ventricle of the brain. It produces melatonin and serotonin and may be involved in mood and timing the onset of puberty.So, the correct answer is option (d).

Explanation for incorrect answer :

Option (a) Brainstem. Breathing is controlled at two levels; conscious and unconscious. The autonomic, unconscious cycle of breathing is controlled by brainstem respiratory centers, such as the ventral respiratory group, dorsal respiratory group and pontine respiratory group.So, this is an incorrect option.

Option (b) Pons. Pontine respiratory group is present in pons.Neurons in the pons compose the pneumotaxic center. Input to the pneumotaxic center includes the cerebral cortex are conducted to the dorsal respiratory group and the ventral respiratory group and the respiratory rhythm gets modified. So, this is an incorrect answer.

Option (c) Medulla oblongata.The ventral respiratory group and the dorsal respiratory group which control the autonomic, unconscious cycle of breathing is present in medulla oblongata.So, this is an incorrect answer.

1. In vivo testing provides valuable insight into a drug’s kinetics. Assessing drug kinetics following multiple different routes of administration provides greater insight than just a single route of administration alone. The following data was collected in 250 g rats following bolus iv, oral (po), and intraperitoneal (ip) administration.Using this data and set of graphs, determine: (a) k, C0, V, and AUC* for the bolus iv data (b) k, ka, B1, and AUC* for the po data (c) k, ka, B1, and AUC* for the ip data (d) relative bioavailability for po vs ip, Fpo/Fip (e) absolute po bioavailability, (f)Fpo absolute ip bioavailability, Fip MAKE SURE ANSWERS HAVE UNITS if appropriate. SHOW ALL WORK, including equation used, variables used and each step to your solution.

2. Drug quantification from plasma is commonly performed by using techniques such as HPLC or LC/MS. However, these methods do have limitations, and investigators may choose to use a radiolabeled analog of a drug instead. Radioligands are molecules that contain radioactive isotopes, commonly 3H or 14C. This technique allows investigators to quantify drug concentration from radiation measurements. The following measurements were made in 250 g rats following oral administration of 18.2 µCi of a 14C-labeled drug of interest: Time (min) Plasma Radiation Levels (µCi/L) 0 0.0 2 9.7 4 19.2 7 25.3 9 37.8 12 39.6 14 45.8 17 48.8 20 52.0 25 56.4 30 59.2 35 60.1 40 61.1 45 62.1 50 62.8 60 63.1 70 62.1 80 60.1 90 57.3 100 55.5 110 53.7 120 52.2 150 48.0 180 45.0 240 39.0 Note that a µCi is a measure of the amount of radioactivity and hence is a measure of the amount of drug present. Given that the oral bioavailability of this drug is known to be essentially 100%, estimate the following from this…
