An elephant's trunk does not have any bones. However, it has many muscles, and the tip has very precise movements that allow it to pick a single leaf from a tree. What type of skeleton allows this movement to occur?

A reflex arc differs from other responses to stimuli in that ____________________.

The genus Latrodectus includes several species, including spiders commonly called widow spiders. The black widow is perhaps the most notorious member of this genus, and some species of black widows exhibit the familiar red hourglass on their ventral side. Black widows have large venom glands, and their bite can be harmful to humans. However, these bites very seldom lead to death in humans if proper medical treatment is provided. In comparison with females, adult male black widows are often gray or brown in color, rather than black, and they are only about half the size of females. As a result, they have smaller venom glands and tend to be less of a health concern. Black widows produce a neurotoxin called latrotoxin, and as the venom spreads through the body, it causes the release of neurotransmitters, including acetylcholine. Black widows spend their entire lives in their cobwebs, sitting and awaiting predators. When a prey item stumbles into their web, they rush out quickly to subdue it but tend to fatigue quickly and cannot maintain high levels of activity for long periods. As a result, ____________________.

Which of the following correctly lists structures in order starting at the outer ear?
