The frontal lobe is located at the front of each cerebral hemisphere and positioned in front of the parietal lobe and above and in front of the temporal lobe.It is separated from the parietal lobe by a space between tissues called the central sulcus, and from the temporal lobe by a deep fold called the lateral sulcus, also called the Sylvian fissure.
Myelination is a process by which axons are covered with a protective substance called myelin that drastically increases the signaling efficiency of the neuron. [7] The arcuate fasciculus is heavily myelinated in healthy adult brains.

The shape of the central sulcus has been linked to the degree of disability in individuals who have a small subcortical ischemic stroke as a result of severe cerebral small vessel disease. [15] However, the severity of the disability has been found to not be fully dependent upon the morphology of the central sulcus. [15]
This separation means that a bronchopulmonary segment can be surgically removed without affecting the function of the others. [ 3 ] There are ten bronchopulmonary segments in the right lung: three in the superior lobe, two in the middle lobe, and five in the inferior lobe.
Animation. Parietal lobe (red) of left cerebral hemisphere. The parietal lobe is defined by three anatomical boundaries: The central sulcus separates the parietal lobe from the frontal lobe; the parieto-occipital sulcus separates the parietal and occipital lobes; the lateral sulcus (sylvian fissure) is the most lateral boundary, separating it from the temporal lobe; and the longitudinal ...
This left frontal lobe brain area (Broca's area) is an important speech production region. The motor aspects of speech production deficits caused by damage to Broca's area are known as expressive aphasia. In clinical assessment of this type of aphasia, patients have difficulty producing speech. [36]
Human anatomy is the scientific study of the morphology of the adult human. It is subdivided into gross anatomy and microscopic anatomy . Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision.
