Anatomy Course A branch of the common tibular nerve. It runs down the posteromedial aspect of the calf. Clinical Damage to the nerve will result in a loss of sensation in the skin on the anterior and posterior portions of the medial calf. Supply Provides sensory innervation to the skin on some of the anterior
Supply Motor supply to the quadriceps femoris as well as many other muscles in the thigh. Cutaneous supply of the anterior and lateral thigh. Anatomy There are two anterior cutaneous branches of the femoral nerve: Intermediate femoral cutaneous nerve and Medial femoral cutaneous nerve. Course The femoral nerve is the largest branch of the lumbar
Anatomy Course Branch of the inferior alveolar artery which travels with the mental nerve and mental vein through the mental foramen of the mandible.

Anatomy Comprise Superior and Inferior Mediastinal Nodes. Superior drain from upper chest and neck next to esophagus and trachea, down to root/hilum lung. Inferior drain from level of hilum to lower lobes lungs. Superficial chest structures (skin, breast, shoulder muscles) drain to Axillary Nodes. Deep thorax structures drain to Mediastinal and Bronchopulmonary Nodes. Interested in
Anatomy Course Arises anterior to the axillary artery from the medial and lateral cords of the brachial plexus. It passes through the arm in the anterior compartment on the medial side between the biceps brachii and the brachialis muscle. It then crosses over the medial epicondyle of the humerus. It then enters the forearm from
