Representation of the human head and the limbic
system shows the location of these structures
within the brain and key components such as the
hippocampus, amygdala, and hypothalamus.
The myelin sheath is a protective layer that surrounds
the axons of neurons. First, its primary function is to
facilitate the rapid transmission of nerve impulses.
The myotatic reflexes illustrate the neuromuscular
mechanism that enables involuntary muscle contraction
in response to stretching. First, this reflex is essential
for maintaining muscle tone and posture.
The neuron is the fundamental cell of the nervous
system. It consists of a soma, dendrites, and an axon.
In addition, each component performs specific
functions for signal transmission.
The segmented spinal cord shows its structural
organization, including gray and white matter,
nerve roots, and spinal nerves. This structure is
fundamental for the transmission of signals
between the brain and the body.
The spinal nervous system is an essential component
of the peripheral nervous system and plays a fundamental
role in communication between the spinal cord and the
rest of the body.
The vertebral column is the bony structure that forms
the central axis of the human skeleton and houses the
spinal cord. It also provides support for the body and
protects the central nervous system.
