Answer:
( a ) Voltage gated channels - channel can open and close based on membrane potential. At rest, the channel is closed and it opens at threshold.
Explanation:
Voltage Gated Channels -
It is a channel with a cluster of proteins present in the membrane .
The function of voltage - gated channel is to open for the some values of membrane potential and close for others . In maximum cases , the relation between channel state and membrane potential is probabilistic and requires a time lag . The ion channel can even flip the conformations at an unpredictable times , the membrane potential even determines the rate of transition and the probability per unit time of each and every transition .
Answer:
The answer to the question: The part of the tooth that is covered with enamel, would be: the crown of the tooth.
Explanation:
The human teeth are divided into two parts, a hardened one, which is the one we can see protruding from the gum line, and which is the one that we use to bite, pounce food and chew it before swallowing. This portion of the tooth is called the crown, it is the white, hardened, visible part, and it is covered with enamel to protect it from the mechanical and corrosive forces of both food, and saliva, as well as bacteria. The second portion of the tooth is known as the root, and it is the softer part that is protected and covered by the gums. The root anchors the tooth to the bone structures of the mandible and maxilla.
Answer:
In a non- hospital environment, the best you can do is follows these instructions:
- Rest. Cut back on normal activities to try and help with swelling and pain.
- Ice the area for 20 min., 4 to 8 times a day, with ice wrapped in a towel. This helps with inflammation. During this time, DO NOT apply heat.
- Apply pressure. Wrap an elastic bandage around your back, not too tightly. This helps reduce swelling.
- Go see a doctor that can provide NSAID ( nonsteriodal anti-flammatory drug) to help relieve pain. Chances are you just have a minor back sprain
Explanation:
- Follow-up.
- Apply heat for the first 48 hours
- Warm up and Cool down
- Don't push too hard
