20 Φεβ 2024 · The cerebrum has two halves, called hemispheres. Each half controls functions on the opposite side of the body. So, the left hemisphere controls muscles on the right side of the body, and vice versa.
24 Ιουλ 2023 · Structure and Function. The neural tube gives rise to three primary vesicles: Forebrain (Prosencephalon), Midbrain (Mesencephalon), and Hindbrain (Rhombencephalon). The prosencephalon divides into the Telencephalon and Diencephalon. The mesencephalon does not divide further.
In the developing chordate (including vertebrates), the neural tube is the embryonic precursor to the central nervous system, which is made up of the brain and spinal cord. The neural groove gradually deepens as the neural folds become elevated, and ultimately the folds meet and coalesce in the middle line and convert the groove into the closed ...
Ventricles. The bulges in the neural tube of the embryo develop into the hindbrain, midbrain, and forebrain—divisions common to all vertebrates, from sharks to squirrels to humans. The original hollow structure is commemorated in the form of the ventricles, which are cavities containing cerebrospinal fluid.
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).
Neural tube defects that result in failure of the tube to close have devastating consequences for brain development and mental function. When the anterior neuropore fails to close, that is, the tube remains open at the front of the brain, a defect called anencephaly results (Fig 5B). Anencephaly leads to a failure of forebrain development, and ...
