title: A histochemical study of cholinesterases in arm and forearm muscles of the pigeon and fowl.
abstract: Various arm and forearm muscles of the pigeon and fowl were studied histochemically. Fibres of the muscles from both birds hydrolysed acetyl, butyryl and propionyl thiocholine iodide. With the exception of M. brachialis, all the fibres of the muscles had "en plaque" motor end plates. M. brachialis had "en grappe" endings on all its fibres. The possibility of M. brachialis being a physiologically "slow" muscle is discussed.
