What else can I help you with?
What holes are in the surface of the dendrites or certain cells of the muscles and glands that are shaped only to fit certain neurotransmitters?
receptor sites
Which of the following are the main receptive or input regions found in neurons?
neurofibrils neurofibrils Both are Wrong, but I do not the correct answer. I think it's NISSL CELL The Dendrites provide the receptive surface for communications. (In some types of neurons the cell body provides such surface) Neither neurofibrils or Nissl cell is wrong. The correct answer is the dendrites. Dendrites are the structures on the neruons that are the main receptive surfaces for nerve impulses.
What is the job of the dendrite?
Dendrites connect to other receptive cell (ie. Receptors)
What is a function of dendrites?
They are the main receptive of input regions. They provide an enormous surface area for receiving signals from other neurons. in the brain it collects information. Dendrites give stability to microstructures.
What are the differences between smooth and striated muscle?
Here we are talking about the surface of the muscles..... Smooth muscles have smooth surface while striated muscles have rough surface.....
Which of the muscles on the dorsal surface are shaped like a trapezoid?
The trapezius muscles are the muscles on the dorsal surface that are shaped like a trapezpoid.
The surface on a neuron that discharges synaptic vesicles is the?
The surface on a neuron that discharges synaptic vesicles is the axon terminal. This is where neurotransmitters are released into the synapse to communicate with other neurons or target cells. The release of neurotransmitters is triggered by an action potential traveling down the axon.
When a nerve impulse reaches the end of the axon the tiny sacs that store the neurotransmitters move to the surface and release the neurotranmistters These tiny sacs that store the neurotransmitters?
are called synaptic vesicles. They contain specific neurotransmitters that are released into the synaptic cleft when the nerve impulse reaches the end of the axon. The neurotransmitters then bind to receptors on the neighboring neuron, continuing the signal transmission.
What acts like antennas receiving messages from as many as 10000 other cells and transmitting these messages toward the cell body?
Receptors on cell surface. Dendrites
What group of muscles forms the flesh of the posterior surface of the thigh?
The hamstrings are the group of muscles that form the flesh of the posterior surface of the thigh. They consist of the biceps femoris, semitendinosus, and semimembranosus muscles. These muscles are responsible for knee flexion and hip extension.
When you sit on a hard surface your muscles harden?
No. Only if you get sat upon.
Muscles visible at the body surface are often called?
externus or superficialis
