ELEN [110]

Answer:

The options

A)hippocampus

B)basal ganglia

C)hypothalamus

D)cerebellum

The CORRECT ANSWER IS D)

D)cerebellum

Explanation:

Apart from the coordinating process, the cerebellum is involved in motor learning, emotional behavior, and fear memory.

Fear learning is widely shown in the variation of autonomic and somatic responses, as in heart rate and freezing, promoted by a neutral stimulus which could have been formally grouped with a painful one.

Variation or changes of the vermis influences these responses, and its reversible inactivation in the period of consolidation which is seen to impair fear memory.

The neural correlate of cerebellar activities in fear consolidation is shown by a behaviorally promoted long-term rise of synaptic effectiveness and efficiencies among parallel fibers and a Purkinje cell.

Likely synaptic variations after fear conditioning are well fully observed in the amygdala and hippocampus, suggesting an interplay among emotional circumstances of scenario and the different variations in neural process.

Furthermore, in hotfoot mice, that shows a basic lack of parallel fiber to Purkinje cell synapse, short- and long-term fear memories are influenced.

All these data gives a foundational background on the concept that the cerebellum is majorly involved in fear learning.

The functional interplay of the vermis with hypothalamus, amygdala, and hippocampus do infer to a more complex activities of the cerebellum as a form of an united network that basically influences emotional behavior.

Can someone explain how it is possible for a single molecule of steroid hormone to create a significant and lasting response in
Mars2501 [29]

Steroid hormone

  • The cell signaling pathways induced by the steroid hormones regulate specific genes within the cell's DNA. The hormones and receptor complex act as transcription regulators by increasing or decreasing the synthesis of mRNA molecules from specific genes.
  • Steroid hormones are not able to target every cell within the body, so the overall response is slower. They bind to receptors on the cell's surface and the receptors aid in helping the steroid hormones enter the cell.
  • Hormones work by binding to protein receptors either inside target cells or on their plasma membranes. The binding of a steroid hormone forms a hormone-receptor complex that affects gene expression in the nucleus of the target cell.
  • Steroids pass into a cell's nucleus, bind to specific receptors and genes and trigger the cell to make proteins.

Identify and describe the various satellites the orbit in our solar system.
Hitman42 [59]

Answer:

Explanation:

The seven largest natural satellites in the solar system (over 2,500 km in diameter) are the four Jovian Galilean moons - Ganymede, Callisto, Io, and Europa - Saturn's moon Titan, Earth's own Moon, and the satellite captured natural of Neptune Triton.

They move around a larger body. They revolve around these bodies because of their gravitational pull. The orbits that they describe when turning on these bodies can be regular or irregular.

Natural satellites of planets in the Solar System

Mercury → 0.

Venus → 0.

Earth → 1.

Mars → 2.

Jupiter → 79.

Saturn → 82.

Uranus → 27.

Neptune → 14.
