Answer:
The correct answer is option E. only water-soluble hormones use second messengers.
Explanation:
Water soluble hormones can not diffuse through cell membranes as only lipid soluble molecules can pass through the cell membranes and these hormons are not lipid soluble molecules,
These water hormones are usually glycoproteins, peptide and catecholamnies such as TSH, FSH, LH and insulin. these hormones need second messengers because there receptors are present on the plasma membrane.
Thus, the correct answer is option - e. only water-soluble hormones use second messengers.
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.
An unconscious adult victim is gasping for breath and having difficulty breathing. The scene is safe and help has been called. Next you should use the head tilt chin lift procedure.
An unconscious patient is at risk of blocking their airway and suffocating. The main reason for this occurring is due to the tongue. An unconscious patient loses all their muscular tone, and this includes the tongue! The tongue can fall back and block the airway.
This situation is an emergency – without a supply of oxygen reaching the lungs, the patient will suffocate in a matter of minutes.
In CPR, we use the head-tilt, chin-lift method to open the airway.
How to Perform a Head-tilt Chin-lift :
- Kneel next to the patient’s head
- Place one hand on the patient’s forehead and tilt the head gently backward
- Place two fingers under the bony part of their chin and lift the chin vertically upwards
- Take care not to place any pressure on the soft part of the neck as this could obstruct the airway
If a cervical spine injury is suspected, then the modified jaw thrust would be used in place of "head-tilt, chin-lift". The jaw thrust is a technique used on patients with a suspected spinal injury and is used on a supine patient.
