The anterior median line is a sagittal line on the anterior of the head and torso running at midline. External links. Figure 50-1
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 ...
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 ).
Anterior (from Latin ante 'before') describes what is in front, [22] and posterior (from Latin post 'after') describes what is to the back of something. [23] For example, for a dog the nose is anterior to the eyes and the tail is considered the most posterior part; for many fish the gill openings are posterior to the eyes but anterior to the tail.
The medial lemniscus carries axons from most of the body and terminates by synapsing with third-order neurons in the ventral posterolateral nucleus of the thalamus. [3] at the level of the mamillary bodies. Sensory axons transmitting information from the head and neck via the trigeminal nerve synapse at the ventral posteromedial nucleus of the ...
The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas). The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine. The skull can be further subdivided into:
In human anatomy, the facial skeleton of the skull the external surface of the mandible is marked in the median line by a faint ridge, indicating the mandibular symphysis (Latin: symphysis menti) or line of junction where the two lateral halves of the mandible typically fuse in the first year of life (6–9 months after birth).

The anterior axillary line [1] is a coronal line on the anterior torso marked by the anterior axillary fold. It's the imaginary line that runs down from the point midway between the middle of the clavicle and the lateral end of the clavicle. The V 5 ECG lead is placed on the anterior axillary line, horizontally even with V 4. The midaxillary ...
