Answer:
lateral inhibition in the retina
Explanation:
Horizontal cells are in contact with photoreceptor cells through the synapse. One photoreceptor forms an excitatory synapse with horizontal cell in the adjacent regions of the retina while the horizontal cell forms an inhibitory synapse with another photoreceptor.
Hence, as one photoreceptor activates the horizontal cell, the horizontal cell, in turn, inhibits the other photoreceptor cell and thereby reduces the quantity of neurotransmitter released at the bipolar cell. In this way, horizontal cells transmit lateral inhibitory stimulus to the photoreceptor which in turn improves the contrast at the edges of the object.
Answer:
E
Explanation:
The picture shown is the cell membrane made of a phospholipid bilayer and proteins embedded. The phospholipid bilayer is made up of hydrophilic (attracted to water) phosphate heads (D), and hydrophobic (repelled by water) tails (E)
The hydrophobic tails face in the way towards each other, while the heads point outwards towards the cell/extracellular environment.
This is because the hydrophobic tails form a conformation that minimizes their contact with water. So you are least likely to find water at E
Answer:
Row 1
T-tubule
Dihydropyridine (DHP) receptors of the transverse tubule membrane play two roles in excitation-contraction coupling in skeletal muscle: (a) they function as the voltage sensor which undergoes fast transition to control release of calcium from sarcoplasmic reticulum, and (b) they provide the conducting unit of a slowly ...
Row 2
Sarcolemma
Ryanodine receptors (RyRs) are located in the sarcoplasmic/endoplasmic reticulum membrane and are responsible for the release of Ca2+ from intracellular stores during excitation-contraction coupling in both cardiac and skeletal muscle.
