The anterior median line is a sagittal line on the anterior of the head and torso running at midline. External links. Figure 50-1 This page was last edited on 7 ...
Posterior axillary line: A vertical line passing through the posterior axillary fold. Scapular line: A vertical line passing through the inferior angle of the scapula. Paravertebral line: A vertical line corresponding to the tips of the transverse processes of the vertebrae. Posterior median line; Other anatomical lines include: Mid-pupillary ...
Pontine nuclei; Pontine cranial nerve nuclei. Chief or pontine nucleus of the trigeminal nerve sensory nucleus (V); Motor nucleus for the trigeminal nerve (V); Abducens nucleus (VI) ...
Sagittal axis or anterior-posterior axis is the axis perpendicular to the coronal plane, i.e., the one formed by the intersection of the sagittal and the transversal planes Coronal axis , medial-lateral axis , or frontal axis is the axis perpendicular to the sagittal plane, i.e., the one formed by the intersection of the coronal and the ...
About 90% of these fibers leave the pyramids in successive bundles and decussate (cross over) in the anterior median fissure of the medulla oblongata as the pyramidal decussation or motor decussation. Having crossed over at the middle line, they pass down in the posterior part of the lateral funiculus as the lateral corticospinal tract.
Central tegmental tract: Directly anterior to the floor of the fourth ventricle, this is a pathway by which many tracts project up to the cortex and down to the spinal cord. Ventral tegmental area : A dopaminergic nucleus , known as group A10 cells [ 8 ] is located close to the midline on the floor of the midbrain.
The mid-clavicular line, a line running vertically down the surface of the body passing through the midpoint of the clavicle. In addition, reference may be made to structures at specific levels of the spine (e.g. the 4th cervical vertebra , abbreviated "C4"), or the rib cage (e.g., the 5th intercostal space ).
The medial longitudinal fasciculus (MLF) is a prominent bundle of nerve fibres which pass within the ventral/anterior portion of periaqueductal gray of the mesencephalon (midbrain). [1] It contains the interstitial nucleus of Cajal , responsible for oculomotor control, head posture, and vertical eye movement.
