1 ημέρα πριν · The Brain Stem. The brain stem is the part of the brain that connects the “upper parts” — the cerebrum and cerebellum — with the spinal cord, says Komisarow. It includes the midbrain, the ...
20 Φεβ 2024 · The brain consists of billions of neurons (nerve cells) that communicate through intricate networks. The primary functions of the brain include processing sensory information, regulating bodily functions, forming thoughts and emotions, and storing memories.
24 Ιουλ 2023 · Introduction. The entire nervous system forms via the process called neurulation in which neural tube and neural crest form initially. In the third week of embryogenesis, three germ layers arise, namely, ectoderm, mesoderm, and endoderm, through the process of gastrulation.
30 Οκτ 2023 · The hypothalamus is the principal visceral control center of the brain and mediates a broad range of functions via its connections with the endocrine, autonomic (visceral motor), somatic motor, and limbic systems, maintaining a state of homeostasis.
9 Νοε 2023 · Cerebrum. The cerebrum is the largest and most recognizable part of the brain. It consists of grey matter (the cerebral cortex ) and white matter at the center. The cerebrum is divided into two hemispheres, the left and right, and contains the lobes of the brain (frontal, temporal, parietal, and occipital lobes).
In subject area: Neuroscience. The neural tube is the embryonic structure that develops into the central nervous system, including the brain and spinal cord. It forms through a process called neurulation, which involves the migration and fusion of cells in the neural plate.
For example, nerve impulses concerned with movement of the left arm originate in the right cerebral hemisphere, and information about the orientation, speed, and force of the movement is fed back to the right cerebral hemisphere, through the left half of the cerebellum.
