Answer:
The correct answer will be option- B.
Explanation:
Glomerular filtration rate or GFR is the rate of the volume of filtrate formed by all renal corpuscles of both kidneys per unit time that is 120 ml/ min. The GFR depends on the pressure gradient in the glomerulus mainly its hydrostatic pressure.
The GFR is directly proportional to the glomerular blood pressure as the blood pressure increases, the hydrostatic pressure also increases which increases the GFR as more water and solutes enter the bowman's capsule. With the decrease in the blood vessels, the GFR decreases.
Thus, option- B is the correct answer.
Answer:
The heart is a muscle and therefore it can be stimulated by electrical impulses.
Explanation:
In the heart, the electrical activity is generated in the SA node and conducted from the right atrium to the left atrium in order to contract myocardial cells
Answer:
Pectoralis minor
Explanation:
Pecoralis minor is a thin, triangular muscle lies beneath the pectoralis major muscle. This muscle arises from the third ribs, fourth and fifth ribs.
The pectoralis muscles fans out from the shoulder upper ribs area. This muscle is involved in the coracoid process of scapula. The pectoralis muscle helps in the depression point of the shoulder.
Thus, the correct answer is option (D).
Answer:
Since this question has multiple subquestions in it, I will give you the answer to them as follows:
1. Which neuron would activate a muscle? They are called multipolar neurons, they are found mostly originating from the CNS itself and they are multipolar because when a neuron stimulates a muscle, one signal from just one terminal is not enough; it requires the stimulation from several neurnal terminals.
2. Which neuron would be found in the retina of the eye? A bipolar neuron. This is because these neurons will fulfill a double function: to activate the muscles of the retina, and also they will convey messages taken by the sense of sight, towards the brain for interpretation and integration.
3. Which neuron is a sensory neuron found in a reflex arc? The answer again is a unipolar neuron. These neurons will not reach the brain itself, but rather the reflex arc site on the spinal cord. Their task is to relay sensations from the site that has been stimulated to the spinal cord and from there to the affected place, with the correct response.
4. Which neuron is never myelinated? Again the answer is the bipolar neurons found connecting the retina and the eyes. The reason is that these neurons are capable of relying fast messages to and from the brain, whereas in myelinated ones, messages go slower due to the myeling sheaths.
5. Which neuron is typically involved in the special senses of sight and smell? Once more the answer is the bipolar neurons that are most commonly found connecting the different organs of these two senses. Since these have such unique capabilities: relying information for integration and sensory and motor responses, their action potentials travel fast, and have a short distance to go.
