Question

Ganglion cell: _________ myelinated, fast (12-36 m/s) 3 of them

Answer 1

Ganglion cells are myelinated neurons found in the PNS that transmit visual signals from the retina to the brain. They have fast conduction speeds and play a crucial role in the visual pathway.

Step-by-step explanation:

Ganglion cells are a type of neuron found in the peripheral nervous system (PNS). They are responsible for transmitting visual signals from the retina to the brain via the optic nerve. These cells are myelinated, meaning they are covered in a fatty substance called myelin which speeds up the conduction of electrical signals. Ganglion cells are fast, with conduction speeds ranging from 12-36 m/s.

For example, ganglion cells play a crucial role in the visual pathway. Different types of ganglion cells carry different qualities of the visual signal, such as form, movement, depth, differences in brightness, color, and fine detail. These signals are then transmitted to the brain for processing and interpretation.

Answer 2

Ga-ngl-ion cells are unm-yelin-ated, slow-conducting neurons with speeds ranging from 0.5 to 2 m/s, and there are three major types of them.

Step-by-step explanation:

Gan-gli-on cells are a type of neuron found in the retina of the eye, transmitting visual information from the photoreceptors to the brain. Unlike many other neurons in the peripheral nervous system, gan-gli-on cells are unm-yelin-ated, meaning they lack a my-el-in sheath around their axons. This absence of my-el-in contributes to slower conduction speeds compared to myelinated neurons. The conduction speed of ga-ngli-on cells typically ranges from 0.5 to 2 meters per second.

There are three major types of gan-glio-n cells: pa-ra-sol cells, mi-dget cells, and bist-ratifi-ed cells. Each type has distinct characteristics and plays a specific role in processing visual information before transmitting it to the brain.
