Elapidae: A family of venomous snakes characterized by fixed front fangs and including cobras, kraits, and sea snakes. Bungarus belongs to this family of front-fanged venomous snakes.
Alpha-bungarotoxin: A toxin isolated from many-banded krait venom that binds nicotinic acetylcholine receptors. It exemplifies how krait venom blocks communication between nerves and muscles.
Snakebite: An injury caused when a snake’s teeth pierce skin, sometimes injecting venom. Krait bites are a medically serious form of snakebite.
Bungarus fasciatus: The banded krait, a large venomous snake with alternating black and yellow bands. Its distinctive banding makes it one of the genus’s most recognizable species.
Krait: A common name for venomous snakes in the genus Bungarus. This common name identifies the genus’s members.
Beta-bungarotoxin: A presynaptic neurotoxin found in many-banded krait venom that disrupts neurotransmitter release. This toxin damages nerve terminals rather than merely blocking their receptors.
Neurotoxic envenomation: Poisoning by venom that impairs nervous-system function, often causing weakness or paralysis. Krait bites can cause progressive paralysis through neurotoxic envenomation.
Bungarus candidus: The Malayan krait, a venomous species found in mainland and island Southeast Asia. It is a medically important krait across much of Southeast Asia.
Snake venom: A complex secretion produced by venomous snakes and delivered through specialized fangs. Krait venom is the key biological trait behind their medical significance.
Neuromuscular junction: The synapse where a motor neuron communicates with a muscle fiber. Krait neurotoxins can prevent signals from reaching muscles at this junction.
