Do fat cells have nerve cells?
No. By definition a cell cannot exist within a cell. Cells are comprised of various organelles.
What is the term meaning nerve cell?
you would say what a nerve cell is made of (cell wall, nucleus, membrane...) and then maybe put a diagram at the bottom of your explanation so the reader can fully understand what you mean.
What ion determines the resting membrane potential of nerve and muscle?
The concentrations on Na+ outside the cell and concentrations of K+ inside the cell determine the resting membrane potential.
What does threshold mean in a muscle or nerve cell membrane?
Threshod is the amount of force or exertion that a muscle or nerve cell can withstand at the peak of stimulation. Extending over a threshold can lead to cell over-exertion and possible damage to the internal structures.
What structure controls the passage of substances into and out of the cell?
cell membrane
What is the electrical potential across the cell membrane of a nerve cell or muscle cell when the cell is not active?
resting potential
Do fat cells have nerve cells?
No. By definition a cell cannot exist within a cell. Cells are comprised of various organelles.
What cell is a cell membrane located in?
the "plasma" membrane encases the "exterior" portion of the cell ... human cell walls are comprised of a cellular or "plasma" membrane. the plasma membrane is also called the phoso-lipid bilayer
What is a component of an animal nerve Cell membrane?
A component is the Sodium ion channel.
What is the most common type of phospholipids in the cell membrane of nerve cells?
PHOSPHATIDYLCHOLINE
Which of the following is a characteristic of thiamine nutrition?
It is an integral part of the nerve cell membrane

The concentrations on Na+ outside the cell and concentrations of K+ inside the cell determine the resting membrane potential.
What are nerve cells part?
Axon, Nerve Ending (Presynaptic Terminals), Dendrites, Neuronal Membrane*, and the Cell Body. The parts within the cell body: Nucleus Golgi Apparatus Polyribosomes Neuronal membrane Mitochondrium Endoplasmic Reticulums (Smooth and Rough)
How is nerve impulse conducted along a myelinated nerve fiber?
In non-myelinated axons, the nerve impulse is going to be produced when the action potential accross a membrane makes a wave of depolarization followed by a wave of repolarization. With the absence of the myelin, the impulse is transmitted continuously throughout the membrane. In a non-myelinated nerve, once an end of the cell, the dendrite, is depolarized, the depolarization a.k.a., the action potential, moves along the nerve membrane, and the area of membrane immediately behind the depolarized section becomes repolarized.
What does a human skin and skin of a leaf have in common?
They are both comprised of cells. Their cells both have a nucleus and cell surface membrane.
How does calcium work to help us?
Calcium has at least 2 rules in the body. One is to stregnthen bones so that old people do not get curved backs (osteoporosis, bones with holes). When they are old. A more important rule of Calcium is to increae or decrease the transmission of a nerve impulse. Ca 2 + has a 2 plus charge. When a nerve inpulse arrives ina neuron (nerve cell), it had a negative charge. The nerve impulse is inside the nerve cell membrane. Ca 2 + will be outside the nerve cell membrane. Calcium of + charge will be attracted to the - charge of the nerve impulse. So Ca 2+ will cross the cell membrane into the nerve cell. The basic result is that a + charge crosses into the membrane towards a - charge. The Calcium 2 + is attracted to the nerve impulse made of electorn, a negative charge. A third neuron acting on the 1 st neuron can increase or decrease the transmission of the neurotransmitter from the 1st neuron. To inhibit the neuron transmission, a third neuroin acting on the first will cause GABA to close membrane pores. This will allow less Ca2+ to enter the membrane from outside the 1st cell, thus reducing the amount of neurotransmitter passed to the 2nd (object) cell. Thsi action of reducing the amount of nerotransmitter passed to the object cell (#2) is called presynaptic inhibition. A third cell can cause pre-synaptic facilitation, an increase of neurotransmitter passed from cell 1 to cell the object cell (#2) by opening the pores through which the Ca 2+ can pass accross the cell membrane in cell 1. There is an increae of nerotransmitter pessed to the object cell. Simply put withoput Ca2+ our nerves would not work, and our bones would become like noodles.
