Thalamus acts as a gateway for sensory impulses before they reach the cerebral cortex.

Further Explanation:

The biggest area of the human brain is occupied by the forebrain. The thalamus, the limbic system, the pineal gland and the hypothalamus are the parts of the forebrain. The body's temperature, eating, sleeping, reproductive functions are all controlled by the forebrain.

The thalamus refers to the small structure found inside the brain and it is located just above the brain stem and between the cerebral cortex as well as the midbrain. It has extensive nerve connections to both. The main role of this organ is to relay the motor as well as sensory signals to the cerebral cortex. It also aids in regulating sleep, consciousness, and alertness.

It works as a midline symmetrical structure of 2 halves, within the vertebrate brain and it is located between the midbrain as well as the cerebral cortex. The main product of the embryonic diencephalon is the thalamus. It is widely known to be the gateway for the sensory impulses.

Answer:

Thalamus

Explanation:

The thalamus is a part of the diencephalon which in turn is a part of the forebrain.

It is the gateway or the relay center for sensory impulses as it helps to relay them from the subcortical areas to the cerebral cortex.

The inputs from the receptors are received by the nuclei present in the thalamus, the sensory information is processed by it and then passed on to the cerebral cortex.

In this way, it acts as a gateway for the sensory impulses it receives from the various receptors.

Answer:

A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism. Enzymes are proteins that act as catalysts in biochemical reactions

serg [7]

Scientists have found that extracellular matrix component may induce specific gene expression in the embryonic tissues such as the liver and testes. For this to happen, there must be a direct communication between the extracellular matrix and the developing cells. The Integrins of transmembrane protein would most likely be involved in this kind of induction.

Integrins are the main principal receptors used by the cells of animal to bind to the matrix of extracellular. They are heterodimers and they function as transmembrane linkers between the actin cytoskeleton and the extracellular matrix. A cell can regulate the sticky activity of its integrins from within.

True blue is a rare color in plants. There are some flowers with blue hues but foliage plants tend to be more gray or green than blue. Green- and gold-colored foliage plants are everywhere. This plant is considered the grandfather of all blue-leaved hostas, and its thick, rounded, corrugated blue leaves develop into a 4-foot-wide by 2-foot-tall clump.
