Question:

Why are IM injections in horses given in the cranial third of the neck?

Jannina S.
Answer:

It is thought that the omohyoideus muscle provides some protection from hitting the common carotid artery. The cutaneous colli muscle in the caudal part of the neck may inhibit jugular venipuncture as well.
