Nerve supply of TAP

Question 1

Thoracic wall innervation

Answer 1

Intercostal nerves from T1-T11 from anterior rami of the thoracic spinal nerves

Question 2

Parietal pleura innervation (x 3)

Answer 2

• Costal = intercostal nerve
• Mediastinal = phrenic nerve
• Diaphragmatic = medially by phrenic, peripheral by lower 6 intercostal

Question 3

Visceral pleura innervation

Answer 3

Sympathetic NS from pulmonary plexus = pulmonary branches of the vagus and sympathetic chain

Question 4

Lungs innervation

Answer 4

Pulmonary plexus: sympathetic from sympathetic trunk and parasympathetic from the vagus nerve

Question 5

Diaphragm innervation

Answer 5

Phrenic nerve (C3-C5), peripherally by intercostal nerves (T5-T11) and subcostal nerve (T12)

Question 6

Pericardium innervation

Answer 6

Phrenic nerve to fibrous and serous pericardium, visceral is vagus and sympathetic trunk

Question 7

The heart innervation

Answer 7

Autonomic: sympathetic trunk and parasympathetic (vagus) collection called cardiac plexus (inferior aortic arch), sensory cardiac nerves, SA node and AV node

Question 8

Abdominal muscles innervation

Answer 8

Thoracoabdominal and subcostal nerves (T6-T12), ilioinguinal nerve (L1)

Question 9

Stomach innervation

Answer 9

Muscle movements = celiac plexus and splanchnic nerves, gastric secretions = vagus (right posterior, left anterior)

Question 10

Pancreas innervation

Answer 10

Parasympathetic exocrine secretion (vagus via posterior vagal trunk into coeliac plexus), sympathetic (T5-T10 to coeliac plexus)

Question 11

Spleen innervation

Answer 11

Coeliac plexus

Question 12

Liver innervation

Answer 12

Parenchyma innervated by hepatic plexus, sympathetic from celiac trunk and parasympathetic from vagus,

Question 13

Glisson’s capsule innervation

Answer 13

Lower intercostal nerves

Question 14

Gallbladder innervation

Answer 14

Coeliac plexus

Question 15

Kidneys innervation

Answer 15

Renal sympathetic plexus, renal plexus afferent fibres enter spinal cord at 10th 11th and 12th thoracic nerves (regulate blood flow)

Question 16

Ureters innervation

Answer 16

Sympathetic renal nerves arise from superior mesenteric ganglion (T10,T11) from splanchnic, afferent fibres enter spinal cord at 10th 11th and 12th thoracic nerves (regulate blood flow)

Question 17

finish rest when on it
