Where do Preganglionic neurons develop from?
Neural crest cells
What happens to neural crest cells?
the produce sexual cells, while the metosis dies because of doing it
What type of neural tissue compose the corpus callosum?
glial cells
Computer circuits that stimulate the brain's interconnected nerve cells?
neural networks
The mechanical vibrations triggered by sound waves are transformed into neural impulses by what?
hair cells
Where do Preganglionic neurons develop from?
Neural crest cells
What is formed from neural crest cells?
central nervous system, spinal cord
What happens to neural crest cells?
the produce sexual cells, while the metosis dies because of doing it
Where are melanocyte cells derived from?
Melanocytes are derived from a structure in the human embryo called the neural crest.
Cells are organized into blank such as muscle neural and cardiac?
Cells that are the same form tissues. Muscle cells form muscle tissue.
What are neural cells?
A nerve cell is the structural and functional unit of a nerve
Muscle cells gland cells and specialized cells that respond to neural stimuli are called?
effectors
The receptor cells that convert light energy into neural signals are called?
Bipolar cells
What is a neurohormone?
A neurohormone is a hormone that is secreted and circulated by neurosecretory cells into the blood. It stimulates neural mechanisms when activated by neural stimuli.
In a toad embryo the neural tube does what?
The neural tube is the embryonic predecessor of the brain and spinal cord. Which means, most of what it "does" is develop into a brain and spinal cord. The neural tube is initially formed almost exclusively of stem and progenitor cells. Over time, these stem and progenitor cells adopt specific identities and begin to differentiate neurons and later glial cells and these cells begin forming neural circuits. By the time the neural tube has developed to a point where it is capable of carrying out rudimentary neurological functions, the nomenclature is generally changed to brain and spinal cord rather than neural tube.
Which week of pregnancy is the neural tube is formed?
In the 3rd week of pregnancy called gastrulation, specialized cells on the dorsal side of the fetus begin to change shape and form the neural tube.
What type of neural tissue compose the corpus callosum?
glial cells
