glossopharyngeal nerve (IX)
The tip of the tongue is supplied by the lingual nerve, a branch of the mandibular division of the trigeminal nerve (CN V3). It provides sensory innervation to the anterior two-thirds of the tongue, including the tip.
The cranial nerve pair being tested by asking the patient to stick out their tongue is the hypoglossal nerve (CN XII). Dysfunction of this nerve can result in a deviation of the tongue towards the affected side, weakness or atrophy of the tongue muscles, and difficulty with speech and swallowing.
hypoglossal nerve
Hitting a nerve while drawing blood can cause nerve damage to the patient. This is very serious and can result in a permanent disability.
The chorda tympani nerve, a branch of the facial nerve, serves the anterior two-thirds of the tongue for taste sensation.
The tongue connects to the brain through a network of nerves, primarily the hypoglossal nerve (cranial nerve XII), which controls its movement. Additionally, sensory information from the tongue, including taste, is transmitted to the brain via the facial nerve (cranial nerve VII) for the front two-thirds of the tongue and the glossopharyngeal nerve (cranial nerve IX) for the back third. These pathways enable the brain to process taste, texture, and temperature, allowing for coordinated movements and sensory experiences.
Hitting a nerve while giving a shot can cause pain, numbness, tingling, or weakness in the affected area. It is important to stop immediately if you suspect you have hit a nerve and seek medical advice to determine the extent of the injury.

You get shocked, but not through your heart, so it won't be pleasant, but it won't kill you.
