Liliequist membrane may be understood as a projection formed by an arachnoid membrane extending from the dorsum sellae to the mammillary bodies coined after Liliequist (1956). It has surgical importance in Endoscopic third ventriculostomy and cisternostomy.
Before embarking on an approach, the surgeon should be familiar with both the ventricular anatomy and the options for optimally Accessing lesions in third ventricle is a surgical challenge because of its difficult corridor as well as deeper location, need of neural incision, preservation of vascular, thalamus and hypothalamus and likely risk of fornix injury.

Muscle Testing of Neck & Scapula
Prof. Satyen Bhattacharyya
Associate Professor: BIMLS, Bardhaman
Chief Physio: Fit O Fine
Director: Well O Fit Healthcare PVT. LTD.
Neck Manual Muscle Testing
Neck Flexion
Origin: Anterior and superior manubrium and superior medial third of clavicle
Insertion: Lateral aspect of mastoid process and anterior half of superior nuchal line
Nerve supply: Axillary Nerve
Note
Factors Limiting Motion:
1- Tension of posterior longitudinal ligament, ligamenta flava, and interspinal and supraspinal ligaments
2- Tension of posterior muscles of neck
3- Apposition of lower lips of vertebral bodies anteriorly with surfaces of subjacent vertebrae
4- Compression of intervertebral fibrocartilages in front
Fixation:
1- Contraction of anterior abdominal muscles
2-Weight of thorax and upper extremities
Normal & Good
Position: Supine.
Stabilization: Stabilize lower thorax.
Desired Motion: Patient flexes cervical spine through range of motion.
Resistance: Is given on forehead
Note
If there is a difference in strength of the two Sternocleidomastoideus muscles, they may be tested separately by rotation of head to one side and flexion of neck.
Resistance is given above ear.
Fair & Poor
Position: supine.
Stabilization: Stabilize lower thorax.
Desired Motion: Patient flexes cervical spine through full ROM for fair grade and through partial range for poor.
Trace & Zero
The Sternocleidomastoideus muscles maybe palpated on each side of neck as patient attempts to flex.
Muscles contribute to Neck Extension
Splenius capitis
Origin: Lower ligament nuchae, spinous processes and supraspinous ligaments T1-3
Insertion: Lateral occiput between superior and inferior nuchal lines
Nerve supply: Greater occipital nerve
Trapezius (superior fibers)
Origin: Base of the skull & posterior
ligaments of the neck
Insertion: Posterior aspect of the lateral 3rd of clavicle
N. supply: Greater occipital nerve
Splenius cervicis
Origin: Spinous processes and supraspinous ligaments of T3-T6
Insertion: Posterior tubercles of transverse processes of C1-C3
Action: Neck Extension
Nerve supply:
Semispinalis capitis
Origin: Transverse processes of first 6 or 7 thoracic and 7th cervical vertebrae & Articular processes of fourth, fifth and sixth cervical vertebrae
Insertion: Between superior & inferior nuchal lines of occipital bone
Nerve supply: Greater occipital nerve
Note
Factors Limiting Motion:
1-Tension of anterior longitudinal ligament of spine
2-Tension of ventral neck muscles
3-Approximation of spinous processes
Fixation:
1-Contraction of spinal extensor muscles of thorax and depressor muscles of scapulae and clavicles
2- Weight of trunk and upper extremities
Normal & Good
Position: Prone with neck in flexion.
Stabilization: Stabilize upper thoracic area and scapulae.
Desired Motion: Patient extends cervical spine through ROM.
Resistance: Is given on occiput.
Fair & Poor
Position: Prone with neck flexed.

USMLE MSK L013 Upper 02 Muscles of scapular, pectoral and deltoid regions.pdfAHMED ASHOUR
The muscles in the scapular, deltoid, and pectoral regions play a crucial role in the movements and stability of the shoulder complex.
These muscles work in coordination to provide stability to the scapula, enable a wide range of shoulder movements, and contribute to the overall function of the upper limb.
Proper functioning of these muscles is essential for activities involving the shoulder complex, such as reaching, lifting, and throwing.
