The deepest layer of the transversospinalis muscle group. 

Origin: Transverse process of each vertebra.

Insertion: Base of spinous process of adjointing vertebra above.

Anatomy of the femoral nerve, what it supplies and associated visceral structures.

Dextroscoliosis of the lumbar spine with right-leaning curvature of the lower back or lumbar spine. 

A left side curvature is known as levoscoliosis.

Also known as the 'labourer's nerve'. The median nerve supplies the muscles of the front of the forearm and muscles of the thenar eminence, thus controlling the coarse movements of the hand. 

The radial nerve contains nerve roots C5 to T1 and terminates into two branches; the deep (motor) and superficial (sensory) branch.

Ulnar nerve neuropathy, its course and cutaneous innervation. 

The radial nerve originates from the brachial plexus and fibers from the ventral roots of spinal nerves C5, C6, C7, C8 & T1. 

The nerve divides into a deep branch which becomes the posterior interosseous nerve and a superficial branch, which goes on to innervate the dorsum (back) of the hand.

The facial nerve is the seventh cranial nerve that contains motor, sensory and parasympathetic (secretomotor) nerve fibres. The nerve provides innervation to many areas of the head and neck. 

The facial nerve supplies: 

- Frontalis

- Orbicularis oculi  

- Orbicularis oris 

- Depressor anguli oris 

- Mentalis 

- Depressor labii inferioris 

- Corrugator 

The Trigeminal nerve is one of 12 cranial nerves and is responsible for sensations in the face and mouth along with motor functions such as biting and chewing. The foramina or openings which the nerves 

pass through have also been labeled. 

Here, the foramen of the cranium have been mainly labelled from a lateral, posterior view perspective.

Foramen in the skull are openings within the cranium which allow structures such as cranial nerves, arteries and veins to pass through them. These then help supply organs such as the brain and eyes along with other structures such as muscles, ears and nose.

The fifth (CN V), the largest and most  complex of cranial nerves (CN V) and responsible for sensation in the face and motor functions such as biting and chewing.

The hamstings consist of three muscles; the biceps femoris, the semitendinosus and semimembranosus which are often affected with sciatica along with the piriformis muscle. Tightness within these muscles can cause radiating pains and altered sensations to the lower limb including the foot. 

Also referred to as the 'pecs muscles'. 

The function of the pectoralis major is to allow adduction, internally rotation, flexion and extension of the arm. 

The pectoralis minor stabilises the scapula against the rib cage along with depression, abduction or protraction, internal rotation and downward rotation of the scapula.

It elevates the ribs for deep inspiration 

and acts as an accessory muscle of inspiration.

The Brachial Plexus is a network of nerves which emerge and send signals from the spinal cord into the upper limb of the shoulder, arm and hand. The intertwined nerves are important as they control movement and sensation in the arm and hand. 

The neural course and it's anatomical branches  of the Median nerve which supplies the front forearm muscles and thenar eminence. The median nerve is also known as the 'labourer's nerve' as it controls the main movements of the hand. 

Elevates and helps retract the scapula as well as aid lateral flexion of the neck. 

Upper fibres of the levator scapulae can often become tight to create neck pain, joint stiffness and headaches 

The radial nerve supplies the posterior (outer) portion of the upper limb in the human body. It supplies most the triceps muscle (medial, long and lateral heads) and the lower, outer forearm. 

The sciatic nerve originates from the ventral rami of nerve roots L4 to S3. 

Cranial sutures are fibrous joints that connect bones of the skull. Sutures allow the bones to move during the birth process .

The sciatic nerve travels all the way down the leg to supply both the dorsal and plantar aspects of the foot
