The upper often faintly marked is named the highest nuchal line but is sometimes referred to as the Mempin line or linea suprema and it attaches to the epicranial aponeurosis. HilariaPesce31 Oktober 02 2021.
The nuchal lines are four curved lines on the external surface of the occipital bone.
Superior and inferior temporal lines. The temporal line is a curved ridge thats found on both sides of the human skull. Its actually made up of two lines with one sitting above the other almost parallel. The higher of the two lines is called the superior temporal line and the lower one is called the inferior temporal line.
The temporal fossa is a depression in the temporal region. It is one of the largest landmarks of the skull. The frontal bone sphenoid bone parietal bone and temporal bone all contribute to the concavity of the fossa.
The temporal lines are the superior border and the zygomatic arch is the inferior border. 17 Superior And Inferior Temporal Lines - Print Neuro Lab Block I- Brain Stem Gross Anatomy. HilariaPesce31 Oktober 02 2021.

Superior and inferior temporal lines. Both superiorly and posteriorly the temporal fossa is bordered by the superior temporal line origin of the deep temporal fascia. The inferior border runs along the zygomatic arch.
Lastly the anterior border is marked by the frontal process of the zygoma and the. The superior temporal line represents the attachment point of the temporal fascia. Superior to this line is the epicranial aponeurosis while inferior to it is the temporal fossa.
Inferior temporal line which forms an identical arch to the previous one but located more inferiorly. It represents the origin of the temporal muscle. Both parietal bones have a temporal line or more precisely they each have a superior and an inferior temporal line.
These lines are external only because their purpose is as attachment points for the temporal muscle and the temporal fascia. An imaginary vertical and horizontal line through the macular anatomically divides the retina into nasaltemporal superiorinferior halves respectively. Nasal axons subserve the temporal half of vision temporal axons the nasal hemifield superior axons the lower visual field and inferior axons the superior.
According to traquairs analogy visual field is an island of vision surrounded by a sea of darkness. It is a 3D hill peak being fovea and at ground level it extends 50 superiorly 60 nasally 70 inferiorly and 90 temporally. Normal blind spot is 15 temporal.
Superior and inferior temporal lines arecrossing the middle of the bone in an arched direction in two curved lines. The former gives attachment to the temporal fascia and the latter indicates the upper limit of the muscular origin of the Temporalis. This definition incorporates text from a public domain edition of Grays Anatomy 20th US.
Temporal lines dominate the ectocranial surface arching anteroposteriorly. The superior temporal line anchors the temporal fascia. The inferior temporal line indicates the most superior extent of the temporalis muscle.
When present the parietal foramen is located close to the sagittal suture near lambda. It transmits a small vein through the parietal to the superior sagittal sinus. Temporal Region Fossa Boundaries.

The lateral surface of the temporal lobe consists of three parallel gyri. Superior middle and inferior temporal gyri. These gyri are separated by the superior and inferior temporal sulci.
The lateral parietotemporal line red dashed line an imaginary line connecting the preoccipital. Single layered - attached to superior temporal line. Two layers- attached to inner and outer lips of upper border of the zygomatic arch.
Gap contains fat Middle temporal artery- branch from superficial temporal artery zygomatico- temporal nerve. Superficial surface receives an expansion from epicranial aponeurosis. The inferior temporal line begins with the superior temporal line and separates from its lower edge to form a parallel but tighter and lower arch.
The inferior temporal line marks the origin of the temporalis muscle. The superior temporal line marks the attachment of the muscles fascia. Externally the squamous portion of the temporal bone is smooth and provides attachment for the temporalis fascia and muscle at the superior and inferior temporal lines respectively.
The zygomatic process which has an anterior and posterior root extends anteriorly and. The figure shows a right bone and number 1 indicates the anterior superior iliac spine. The figure shows a left bone and number 6 indicates the ischial tuberosity.

The upper often faintly marked is named the highest nuchal line but is sometimes referred to as the Mempin line or linea suprema and it attaches to the epicranial aponeurosis. Below the highest nuchal line is the superior nuchal lineTo it is attached the splenius capitis muscle the trapezius muscle. Pair of temporal lines Superior and inferior temporal lines that arch from the zygomatic process of the frontal bone to the supramastoid crest of the temporal bone.
Temporal fascia a fan-shaped aponeurosis overlying the temporalis muscle. Frontal temporal and maxilla Temporal and maxilla Temporal and parietal Frontal parietal and occipital Temporal sphenoid and maxilla. Horizontal line drawn between disc centre and fovea and the perpendicular to this IFS was constructed to reach the inferior and superior temporal veins.
Lines from points I and S to the optic disc centre enabled angles SVA superior vessel angle and IVA inferior vessel angle subtended at the optic disc to be calculated.
