Answer: Cervical canal
Explanation:
The process by which male gamete and female gamete fuse together to form a zygote is known as fertilization.
During sexual intercourse millions of sperms are released from penis that reaches the vagina and gets stored there temporarily. The sperm from vagina travels through the cervical canal to move into the uterine cavity.
From there it reaches the Fallopian tube. Hence, the correct answer is cervical canal.
Answer:
Kindly check explanation as the question seems incomplete but the explanation should help.
Explanation:
Given the following :
Initial dosage of drug = 100mg
Halflife of drug = 6hours
After 18 hours, the percentage of drug that will be in the system should be :
Half-life is the time taken for a material to reduce to half of it's initial size.
Since half life = 6 hours
After 6 hours ; amount left = 100/2 = 50 mg
After 12 hours ; amount left = 50/2 = 25mg
After 18 hours ; amount left = 25/2 = 12.5mg
Hence, after 18 hours percentage left in system :
(Amount left / total initial amount) × 100%
(12.5 / 100) × 100%
0.125 × 100%
= 12.5%
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.
