What else can I help you with?
Does the neuron respond to all impulses?
Yes a neuron will always respond to the binding of neurotransmitters released from another cell (synaptic transmission being the 'impulse'). Depending on which neurotransmitter was bound, the postsynaptic potential of the membrane will become either more positive or more negative. It is the summation of these inputs and membrane potentials that determine whether the cell will subsequently fire an action potential.
Is Cutaneous membrane a dry membrane exposed to air?
Yes, that would be a fair statement although your skin always has a degree of oil deposits on it to help with moisturizing.
What tissue always maintains a basement membrane?
Epithelial tissue always maintains a basement membrane, which is a thin layer of extracellular matrix that separates the epithelium from underlying connective tissue. This membrane provides structural support, regulates the exchange of molecules, and plays a crucial role in tissue repair and regeneration. The basement membrane is essential for the integrity and function of epithelial tissues throughout the body.
The motion phospholipids make in a plasma membrane?
Phospholipids in a plasma membrane exhibit lateral diffusion, allowing them to move sideways within the plane of the membrane. They can also undergo flexion and rotation, enabling the membrane to adjust to changes in shape and movement of the surrounding molecules. These motions collectively contribute to the fluidity and dynamic nature of the plasma membrane.
What form of passive transport always requires membrane-bound proteins?
Facilitated diffusion
What is the rule of conduction?
· Law of forward conduction: a theory that nerve impulses always travel from postsynaptic membrane of the dendrites to the terminal knob of the axon. The law of forward conduction prevails in nature, but the direction can be reversed under experimental laboratory conditions.
Does the neuron respond to all impulses?
Yes a neuron will always respond to the binding of neurotransmitters released from another cell (synaptic transmission being the 'impulse'). Depending on which neurotransmitter was bound, the postsynaptic potential of the membrane will become either more positive or more negative. It is the summation of these inputs and membrane potentials that determine whether the cell will subsequently fire an action potential.
What is the function of a neuron's dendries?
In general, but not always, dendrites receive neurochemical information from neurotransmitters released by axons. Dendrites are branched extensions of the neuronal cell body, or soma, that receive information from other neurons. The dendrite is the post-synaptic portion of many synapses within the nervous system that contains synaptic receptors that bind to neurotransmitters and respond by excitation or inhibition of the membrane potential.
Does diffusion always have to be though a membrane?
yes
Are neurotransmitters always stimulatory?
No, neurotransmitters can be either stimulatory or inhibitory. Stimulatory neurotransmitters excite the receiving neuron and increase the likelihood of an action potential, while inhibitory neurotransmitters decrease the likelihood of an action potential. Both types are essential for maintaining a balance in neural signaling within the brain and nervous system.
What neurotransmitter is always excitatory?
Glutamate is the primary excitatory neurotransmitter in the central nervous system. It enhances the transmission of signals between neurons by promoting the depolarization of postsynaptic neurons.
Is Cutaneous membrane a dry membrane exposed to air?
Yes, that would be a fair statement although your skin always has a degree of oil deposits on it to help with moisturizing.
Why the effects of neurotransmitter binding are very brief?
Neurotransmitter binding are designed to be brief so that another one can be initiated if needed. Failure to break down neurotransmitters so that a signal is always activated can be disasterous to a biological organism. In fact, nerve gases, (e.g. sarin) work by inhibiting the enzyme cholinesterase, which breaks down acetylcholine in autonomic nerve synapses and neuromuscular junctions.

Osmosis always involves the movement of what?
Osmosis always involves the movement of water. During osmosis water will move in and out of the cell or membrane.
What is Something that is always in plants?
A seed and a cell membrane, cell wall, cytoplasm, nucleus
