Vestibulocochlear nerve | Vestibular system
The vestibular ganglion (also called Scarpa's ganglion) is the ganglion of the vestibular nerve. It is located inside the internal auditory meatus. The ganglion contains the cell bodies of bipolar neurons whose peripheral processes form synaptic contact with hair cells of the vestibular sensory end organs. These include hair cells of the cristae ampullares of the semicircular duct and macula in the utricle and saccule. It is named for Antonio Scarpa. At birth, it is already close to its final size.

Ring Definition (expanded) - Abstract Algebra
A ring is a commutative group under addition that has a second operation: multiplication. These generalize a wide variety of mathematical objects like the integers, polynomials, matrices, modular arithmetic, and more. In this video we will take an in depth look at the definition of a rin

Definition of a group Lesson 24
In this video we take our first look at the definition of a group. It is basically a set of elements and the operation defined on them. If this set of elements and the operation defined on them obey the properties of closure and associativity, and if one of the elements is the identity el

Phylum Chaetognatha: Arrow Worms
The organisms in phylum Chaetognatha are known as arrow-worms, or bristle-jaws. They have a very interesting anatomy and eating habits. Their phylogeny is tricky and still in flux, so let's learn about what we know right now! Script by Ryan Helcoski and Dr. Carsten H G Müller: https://www

Symmetric Groups (Abstract Algebra)
Symmetric groups are some of the most essential types of finite groups. A symmetric group is the group of permutations on a set. The group of permutations on a set of n-elements is denoted S_n. Symmetric groups capture the history of abstract algebra, provide a wide range of examples in
