Anatomy Course Arises from the posterior trunk of the mandibular nerve (V3), and also carries fibres from the facial nerve (VII). The lingual nerve first arises between the lateral pterygoid muscle and the tensor palatine muscle. It is then joined by the branches from the facial nerve (VII) via the chorda tympani nerve, while it

Anatomy Round areas of lymphoid tissue on dorsal surface of root/back of the tongue. Clinical Tonsils (Lingual, Palatine, Pharyngeal) are masses of Lymphoid tissue with 10-20 crypts, constituting the first defences met by inhaled, eaten and drunk pathogens/antigens. Component of MALT (Mucosa Associated Lymphoid Tissue). Interested in taking our award-winning Pocket Anatomy app for a

Anatomy Origin: Body of the pubis, tendinous arch of obturator fascia and pelvic surface of ischial spine. Insertion: Coccyx, around the anal canal and the anococcygeal ligament. Key Relations: -Forms posterior part of the levator ani muscle. -Contributes to formation of the pelvic diaphragm in association with coccygeus (for more information see the above layer)

Anatomy Course Branches from the axillary artery, beyond the lateral margin of pectoralis minor. It then travels inferomedially on the thoracic wall, following the pectoralis minor muscle. It terminates here, anastomosing with intercostal vessels, internal thoracic arteries and the subscapular artery. Supply Contributes to the blood supply of the front wall of the axilla, the

Anatomy Origin: Maxilla inferior to the infra-orbital foramen. Insertion: Skin at the corner of the mouth. Key Relations: Lies posterior to levator labii superioris, levator labii superioris alaeque nasi and zygomaticus major and minor. Functions Raises corner of the mouth and forms the nasolabial furrow e.g. during sadness.. Supply Nerve Supply: Buccal branch of the

Anatomy Course Originates laterally from the dorsal venous arch of the foot. It ascends superficially on the posterior aspect of the leg until it pierces the deep fascia and joins the popliteal vein. Drain The lesser saphenous vein drains the superficial leg and foot. Interested in taking our award-winning Pocket Anatomy app for a test

Anatomy Origin: Spinous processes of T7 to T12 and the thoracolumbar fascia, by which it is attached to the spines of all lumbar and sacral vertebrae. The posterior part of the iliac crest and the lower three to four ribs. Insertion: The fibres converge to form a flattened tendon and attaches to the floor of

Anatomy This is a C-shaped cavity within each cerebral hemisphere lined with ependymal cells. They are part of the series of fluid-filled cavities, which make up the ventricular system. It is connected to the third ventricle via the interventricular foramen of Monro. It divides into a body, which occupies the parietal lobe and anterior, posterior

Anatomy Formed from the fusion of the aponeuroses of the abdominal muscles. It forms the midline of the abdomen. It extends from the xiphoid process superiorly to the pubic symphysis inferiorly. Functions The attachment point for the vertical and anterolateral abdominal muscles. Clinical Surgeons tend to make incisions along this line during abdominal surgery due

Anatomy Origin: Posterior tubercles of the transverse processes of the upper four cervical vertebrae (C1 to C4). Insertion: Medial border of the scapula between the superior angle and the spine, opposite the supraspinous fossa. Key Relations: Lies within the floor of the posterior triangle of the neck. Functions -Working with various other muscles of the
