A 67-year-old man presents to accident and emergency with a 3-day history of shortness of breath. On examination you palpate the radial pulse and notice that the patient has an irregular heart beat with an overall rate of 140 bpm. You request an electrocardiogram (ECG) which reveals that the patient is in atrial fibrillation. Which of the following would you expect to see when assessing the JVP?
  1. ক
    Raised JVP with normal waveform
  2. খ
    Large a waves
  3. গ

  4. ঘ
    Absent a waves
সঠিক উত্তর: ঘ
Absent a waves
উত্তর
সঠিক উত্তর: ঘ
Absent a waves
ঘ
ব্যাখ্যা
 The JVP provides clinicians with information regarding right atrial pressures and filling. It mainly consists of five wave forms:
1 a wave - representing atrial systole;
2 c wave - representing closure of the tricuspid valve (this wave is not usually visible);
3 x descent - representing a fall in atrial pressure during ventricular systole;
4 v wave - representing atrial filling against a closed tricuspid valve;
5 y descent - representing the opening of the tricuspid valve.

In atrial fibrillation, the 'a waves' are absent (D) due to dysfunctional atrial systole. A raised JVP with normal waveform pattern (A) is usually seen in fluid overload and right heart failure. Large v waves (B) are usually seen in patients with tricuspid regurgitation. Cannon 'a waves' (C) are seen in patients with complete heart block, single chamber ventricular pacing, ventricular arrhythmias and ventricular ectopics. Large 'a waves' (E) can be seen in pulmonary hypertension and pulmonary stenosis.

Which of the following transport processes is involved if transport of glucose from the intestinal lumen into a small intestinal cell is inhibited by abolishing the usual Na+ gradient across the cell membrane?
  1. ক
    Facilitated diffusion
  2. খ

    Cotransport
  4. ঘ
    Countertransport
সঠিক উত্তর: গ
Cotransport
উত্তর
সঠিক উত্তর: গ
Cotransport
গ
ব্যাখ্যা
Explanations:
In the usual Na+ gradient, the [Na+] is higher in extracellular than in intracellular fluid (maintained by the Na+–K+ pump). Two forms of transport are energized by this Na+ gradient cotransport and countertransport. Because glucose is moving in the same direction as Na+, one can conclude that it is cotransport.

Explanation : Optic tract is formed by uncrossed fibers of optic nerve on the same side and crossed fibers of optic nerve from the opposite side. Fibers from fovea do not enter superior colliculus. Supraoptic nucleus of hypothalamus: It is concerned with the retinal control of pituitary in animals. But in human, it does not play any important role. Fibers from lateral geniculate body pass through internal capsule and form optic radiation.

গ) Increased intracellular Ca2+ concentration
গ
ব্যাখ্যা
Inhibition of Na+,K+-adenosine triphosphatase (ATPase) leads to an increase in intracellular Na+ concentration. Increased intracellular Na+ concentration decreases the Na+ gradient across the cell membrane, thereby inhibiting Na+–Ca2+ exchange and causing an increase in intracellular Ca2+ concentration. Increased intracellular Na+ concentration also inhibits Na+–glucose cotransport.

2. Constriction of the pupil due to the contraction of constrictor pupillae of iris
3. Increase in the anterior curvature of the lens due to contraction of the ciliary muscle.

Explanation : In addition to increase in anterior curvature of the lens, two more adjustments are made in the eyeball during accommodation for near vision.
1. Convergence of both eyeballs: It is necessary to bring the retinal images on to the corresponding points
2. Constriction of pupil: It is necessary to:
i. Increase the visual acuity by reducing lateral chromatic and spherical aberrations
ii. Reduce the quantity of light entering eye
iii. Increase the depth of focus through more central part of lens as its convexity is increased.

The sequential steps are as follows:

1.The bipolar cells of the spiral ganglion, which are located in the cochlea’s modiolus, are the first-order neurons of the auditory pathway.
2. The second-order auditory pathway neurons are made up of neurons from the dorsal and ventral cochlear nuclei in the medulla oblongata.
3. Both the superior olivary nuclei and the lateral lemniscus nucleus comprise the third-order neurons.
4.The subcortical auditory centre is formed by the medial geniculate body, where the fibres of third-order neurons terminate.
5.The nerve fibres from the medial geniculate body travel as auditory radiation via the internal capsule to the temporal cortex.
6.In the midbrain, the inferior colliculus of the tectum receives some fibres from the medial geniculate body.
7.The reflex movements in response to auditory stimuli are mediated by the auditory radiation fibres.
8.The temporal lobe of the cerebral cortex houses the cortical auditory centres. The perception of auditory impulses, analysis of sound pitch and intensity, and identification of sound source are all concerns of the cortical auditory centres.

Second order neurons (secondary neurons) are the ganglionic cells in ganglionic cell layer of retina. Axons of the ganglionic cells form optic nerve. Optic nerve leaves the eye and terminates in lateral geniculate body. Third order neurons are in the lateral geniculate body. Fibers arising from here, reach the visual cortex.

The acetylcholine-gated channel has a diameter of about 0.65 nanometer, which is large enough to allow the important positive ions-sodium (Na+), potassium (K+), and calcium (Ca2+)-to move easily through the opening. Patch clamp studies have shown that one of these channels, when opened by acetylcholine, can transmit 15,000 to 30,000 sodium ions in 1 millisecond. Conversely, negative ions, such as chloride ions, do not pass through because of strong negative charges in the mouth of the channel that repel these negative ions.
