The folded region of the sarcolemma at the neuromuscular junction is called the motor end plate. It is responsible for receiving signals from the motor neuron and initiating muscle contraction. The motor end plate is rich in acetylcholine receptors, which play a key role in neurotransmission at the neuromuscular junction.

Neuromuscular junction is also known as the what?
The NMJ is the region where the efferent motor nerves connect with muscle tissue. When a signal is sent from the brain, down the spinal cord, to the nerve, neurotransmitters are released into the synaptic cleft (primary acetylcholine), which cause the muscle to contract.
What region surrounding the crease in the skin at the junction of the upper leg with the trunk?
The region surrounding the crease in the skin at the junction of the upper leg with the trunk is called the inguinal region. This area is important for lymphatic drainage, blood vessels, and nerves that supply the lower limbs. It is also a common site for hernias to occur due to the natural weakness in the abdominal wall in this area.
Where is the fundic region?
The fundic region is located in the upper part of the stomach, just below the gastroesophageal junction. It is lined with gastric glands that secrete hydrochloric acid and pepsinogen to aid in digestion. The fundic region is responsible for storing and breaking down food that enters the stomach.
What Depletion region will form?
A depletion region will form at the junction of a p-type and n-type semiconductor in a semiconductor diode. This region is depleted of charge carriers, creating an electric field that prevents further flow of current in the reverse bias direction.
The junction of the parietal temporal and occipital association areas is called?
The junction of the parietal, temporal, and occipital association areas is known as the parieto-temporo-occipital (PTO) junction. This region plays a crucial role in integrating sensory information from different modalities and is involved in complex cognitive functions such as visual perception and spatial awareness. Dysfunction in this area can lead to disorders affecting perception, attention, and spatial cognition.

A transistor is in active region when?
a transistor in active region when emitter junction is forward biased nd collector junction is reverse biased
What is the region surrounding the crease in the skin at the junction of the upper leg with the trunk?
The groin is the area surrounding the crease in the skin at the junction of the upper leg with the trunk. The entire region is the pelvic region.
Why a transistor can be operated in active region?
a transistor can only work in active region cox in active region collector base junction is in reverse bias and emitter base junction is in forward bias.
What is the biasing technique in transistor for it to be in active region?
For a transistor to be in active region : Base Emitter junction should be forward biased and Emitter collector junction should be reverse biased.
What will happen to the depletion region when the P-N junction is supplied by forward bias?
depletion region will decrease.
Why is that a space charge region in a pn junction at equilibrium is often made small?
The space charge region in a pn junction at equilibrium is often made small due to:to obtain a high junction capacitance;since the junction capacitance is inversely proportional to the width of the space charge region, the smaller the width, the larger the junction capacitance.to ensure easy diffusion of charge carriers;if the space charge region is made small, that is, the width is made small, the distance for diffusion also becomes short, then it becomes easy for the electrons to diffuse into the p-side and the holes into the n-side
What is space charge region in pn junction?
The depletion region is also called as the space charge region.A p-n junction diode is formed by placing p and n type semiconductor materials in intimate contact on an atomic scale. This may be achieved by diffusing acceptor impurities into an n type silicon crystal or by the opposite sequence.In an open circuit p-n junction diode, majority carriers from either side will diffuse across the junction to the opposite side where they are in minority. These diffusing carriers will leave behind a region of ionized atoms at the immediate vicinity of the metallurgical junction. This region of immobile ionized atoms is called the space charge region.
How depletion region is narrowed during forward biasing?
When the pn junction is forward biased, some of the space charge is neutralized reducing the width of the pn junction.
Region surrounding the crease in the skin at the junction of upper leg with trunk?
inguinal means relating to groin which is the crease at the junction of the trunk and upper end of the thigh.
What region is the junction of descending and sigmoid colons of large intestine?
left iliac crest
Why do the electrons are not atracted by the holes when they move in a diode?
they ARE, but only in close proximity (at the junction). this is what creates the depletion region around the junction: electrons being attracted to holes and falling in. once the depletion region gets wide enough attraction stops.
