One of the mysteries of the English language finally explained.
1A snake that kills by coiling around its prey and asphyxiating it.
Families Boidae and Pythonidae, and some members of other families (in particular Colubridae)
- ‘They are constrictors; they suffocate their prey by coiling around it and squeezing.’
- ‘The monster constrictors can also squeeze the life out much larger prey before swallowing it whole.’
- ‘The cartridge shot out and hit him in the face, breaking his nose, and the power cord wrapped itself like a constrictor around his neck.’
- ‘‘I can deal with the spiders and smaller corn snakes on my own, but the larger ones, such as the constrictors, need two people,’ she said.’
- ‘Asphyxiation was long thought to be the cause of death of constrictors' prey, but recent studies have found that death occurs far too rapidly (in about four minutes) for it to be that alone.’
- ‘But constrictors eat prey that is too big, animals that could do the snake harm.’
- ‘Hundreds of the constrictors - which reach upwards of 19 feet and 200 pounds - are breeding and expanding their range in Florida's wetlands.’
- ‘He rode snakes, one foot each on a huge cobra's back, and jewelsnakes and small constrictors and other serpents adorned his body.’
- ‘This time, I scanned the ledge for the shy constrictor.’
- ‘Apparently, this constrictor was quite a good swimmer.’
- ‘We did one project on rainforest snakes, covering everything from constrictors to vipers.’
- ‘Pythons are constrictors, meaning they rely on strength, not venom, to kill their prey.’
A muscle whose contraction narrows a vessel or passage.
- ‘The tonsillar capsule was dissected away from the underlying superior constrictor muscle with the dissection continued along the anterior tonsillar pillar towards the posterior tonsillar pillar (open book technique).’
- ‘The more inferior fibers arch distally deep to the middle constrictor muscle.’
- ‘The constrictor muscle is supplied by the parasympathetic nervous system, and the dilator by the sympathetic nervous system.’
- ‘Pupillary size is controlled by the action of the constrictor and dilator smooth muscles of the iris.’
- ‘In contrast to these nerves, the pharyngeal branch of the vagus provides the primary motor output to the superior, medial, and inferior pharyngeal constrictor muscles.’
- 2.1 Each of the muscles which constrict the pharynx.
- ‘The muscular walls of the pharynx constitute three overlapping sheets of striated muscle, the pharyngeal constrictors.’
- ‘The muscular wall of the pharynx can be divided into three overlapping segments of striated muscle, termed the pharyngeal constrictors.’
- ‘Included are those fibers joining the inferior constrictor of the pharynx to the thyroid gland.’
- ‘The inferior constrictor is seen for the last time.’
- ‘A thickened band at the caudal extremity of the inferior pharyngeal constrictor forms the upper esophageal sphincter, or cricopharyngeus muscle.’
Early 18th century: modern Latin, from constrict- ‘bound tightly together’, from the verb constringere (see constrain).
