What salivary gland has an opening that is easily noted because of a high elevation of mucous membrane?
The salivary gland with an easily noted opening due to a prominent elevation of the mucous membrane is the parotid gland. The duct of the parotid gland, known as Stensen's duct, opens into the oral cavity at the second upper molar tooth, creating a noticeable papilla. This distinct elevation makes it easy to identify the gland's ductal opening during oral examinations.

Which salivary gland has an opening because of a high elevation of mucous membrane?
The salivary gland with an opening due to a high elevation of the mucous membrane is the parotid gland. Its duct, known as Stensen's duct, opens into the oral cavity at the parotid papilla, which is a small elevation located near the second upper molar. This elevation helps facilitate the secretion of saliva into the mouth.
What cause the membrane potential of a neuron?
Opening or closing of ion channels at one point in the membrane produces a local change in the membrane potential, which causes electric current to flow rapidly to other points in the membrane.
What stapes is attached to this membrane-covered opening?
The stapes is attached to the oval window, which is a membrane-covered opening in the vestibule of the inner ear. It transmits sound vibrations from the ear drum to the cochlea, where they are converted into electrical signals for the brain to process.
What region between the cell membrane and the nucleus is filled with what?
it has pores and opening and it has fluids like water
What effect does the opening of the potassium channels have on the charge difference across the neuron's membrane?
Opening of potassium channels allows potassium ions to move out of the neuron, leading to hyperpolarization by increasing the negative charge inside the neuron. This action increases the charge difference across the membrane, known as the resting membrane potential, making the neuron less likely to fire an action potential.

What is the Opening in the nuclear membrane?
They are called pores.
The membrane stretched over the opening to the middle ear is the?
tympanic membrane, also known as the eardrum, is the membrane stretched over the opening to the middle ear. It plays a vital role in transmitting sound vibrations from the outer ear to the middle ear.
What is the medical term meaning surgical removal of a salivary stone?
A sialolith is the medical term for a salivary stone. Sialolithiasis is the condition of salivary stones.The term for a stone in the salivary gland is Sialolithiasis.SialolithiasisSialolith
Opening of sodium channels in the membrane of a neuron results in?
depolarization.
What causes the opening of sodium voltage-gated channels in the neuronal membrane?
The opening of sodium voltage-gated channels in the neuronal membrane is caused by changes in the electrical charge across the membrane, known as membrane potential. When the membrane potential reaches a certain threshold, the channels open, allowing sodium ions to flow into the neuron and generate an action potential.
An opening formed where the two layers of the nuclear membrane fuse?
pores
The fold of membrane that is sometimes found near the vaginal opening is the?
hymen
The opening of the what is located in the buccal mucosa just opposite the maxillary second molar?
Parotid salivary gland duct, also called Stenson's duct.
What cause the membrane potential of a neuron?
Opening or closing of ion channels at one point in the membrane produces a local change in the membrane potential, which causes electric current to flow rapidly to other points in the membrane.
Compare the locations of the major salivary glands of the human with those of the cat?
The human salivary glands are in front of the ear, above the opening of your throat, and behind and a little under the jaw. They are the same places in cats, excepts cats have an extra one that is under and a little past the eye.
