Answer:
The thalamus of the brain functions in this analogous manner.
Explanation:
The thalamus (dorsal and ventral thalamus) is a structure located in the forebrain, at the base of the cerebrum. It acts as a relay center with nerve fibers project out to the cerebral cortex in all directions.
The thalamus is mainly made up of gray matter and contains a small amount of white matter. The grey matter, which is divided into the anterior part, medial and dorsal part contains several nuclei that interconnect brain activity between different areas of the brain. The anterior part contains anterior thalamic nuclei, medial part contains dorsomedial nuclei and the lateral part contains dorsal tier and ventral tier nuclei. Interlaminar nuclei
, reticular nuclei, medial geniculate body
, lateral geniculate body, etc are other nuclei present in the thalamus.
The thalamus receives sensory information from the various receptors in the body. It relays this sensory information to the cerebral cortex, where it is interpreted as pain, touch, temperature, etc. The various functions of thalamus include the integration of sensory information, emotional control, motor control, integration of sensations with emotions, regulation of consciousness, sleep, and alertness.
First Part of the Cell Theory:
All living things are composed of cells.
Second Part of the Cell Theory:
Cells are the basic unit of structure and function in living things.
Third Part of the Cell Theory:
All cells are produced from other cells.
It results from the composition of the cell membrane. The cell membrane consists of a phospholipid bilayer, which have hydrophilic heads and hydrophobic tails. Hope this helps! :)
Answer:During the second and third trimesters of
gestation androgenic C19 steroid, and dehydroepiandrosterone sulfate (DHEA-S), are secreted by the fetal adrenal gland and human placental lactogen (hPL), is secreted by the placenta.
Explanation:During midgestation, the fetal zone occupies 80–90% of the cortical volume and produces 100–200 mg/day of the androgenic C19 steroid, dehydroepiandrosterone sulfate (DHEA-S), which is quantitatively the principal steroid product of the primate fetal adrenal gland throughout gestation. While human placental lactogen (hPL) may be secreted preferentially into the fetal circulation, exerting growth-promoting effects at a time when the rate of linear growth of the fetus is maximal.
