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.
The appropriate route of administration of promethazine to the patient:
- IM or IV would be the best route for the administration of promethazine for the client.
<h3>What is promethazine?</h3>
Promethazine can also be given orally as an antiemetic but however, if the client is actively vomiting the tablet might be regurgitated before it can be absorbed to elicit its effect. Promethazine is the first generation of antihistamine and antiemetic drugs used to treat allergies, insomnia, and nausea.
It can also help with some of the symptoms associated with the common cold and can also be used to calm people who are restless or have excessive anxiety.

Answer:
Haemorrhage
Explanation:
Haemorrhage The escape of blood from any blood vessels, normally in response to trauma.
Answer:Loss of bone an muscle densi
Explanation:Bone loss occurs in the weightless environment of space because bones no longer have to support the body against gravity. On Earth, gravity applies a constant mechanical load to the skeletal system, that causes healthy bones to maintain a certain density so that they are able to support the body.
Answer:
Sarcomere.
Explanation:
Sarcomere is responsible for the striation of the skeletal and cardiac muscle. The striation was first described by the scientist Van Leeuwenhoek.
Sarcomere may be defined as the basic unit of the striated muscle tissue. This is the repeating unit of two Z lines alternating between the dark and light bands of the striated muscle.
Thus, the answer is sarcomere.
