Dorsal root ganglion
It depends upon what you are referring to as connecting. Most nerve cells do not connect to each other, but pass their impulse from one to the other via synapses. There are also places where nerve cell bodies cluster together in the peripheral nervous system, and this is known as a ganglion. When a group of nerves come close to each other and are covered in connective tissue for protection, it is called a plexus. The nerve do not actually connect to each other, but are wrapped together.
The crayfish has many appendages. In addition to two large claws and eight regular legs, it has ten smaller limbs along the abdomen and tail. These are known as swimmerets, designed to help propel the crustacean through the water.
They are situated on the dorsal root of each spinal nerve. (:
The hilum is the part of the organ where vessels and nerves enter and leave.For most organs vessels and nerves enter an leave all over the place and not always near each other. However in the kidneys and lungs the major blood vessels enter at an area called the hilum.
A statocyst at the base of each antennule enables the crayfish to keep its balance.
I am not sure, but from what I can conclude from diagrams and from a recent dissection no, the crayfish does not have a liver. Although you should consider asking your biology teacher just to be sure.

Anatomy James said:Technically they dont exist. A ganglion is a collection of neuronal cell bodies in the peripheral nervous system. A collection of these cell bodies in the central nervous system is sometimes mistakenly called a ganglion but is actually correctly termed a nucleus.Just C. Urious: The Cerebral Ganglion is the brain of an earthworm
