What else can I help you with?
Where does the efferent pathways of the parasympathetic division originate from as they leave the cns?
They originate from the cranial and sacral regions of the CNS
What forms liquid cushion for the cns structures?
Cerebrospinal fluid (CSF) forms a liquid cushion around the central nervous system (CNS) structures, including the brain and spinal cord. CSF provides buoyancy, protection, and nutrient delivery to these structures. It also helps to remove waste products and maintain appropriate pressure within the CNS.
List the structures of the CNS and PNS?
Peripheral Nervous System (PNS)Contains all nerves outside of the brain & spinal cord.Somatic Nervous System (Voluntary)Two types: Sensory (or afferent) and motor (or efferent) nerves
What are located and protected within the CNS?
The 2 primary structures of the CNS are:The brain, housed in and protected by the skullThe spinal cord, housed in and protected by the vertebral column.
What are two structures of the central nervous system?
The CNS is made up of the brain and the spinal cord.
What two structures are apart of the central nervous system?
The CNS is made up of the brain and the spinal cord.
From what areas of the CNS does each division originate?
The parasympathetic originates from the brain and spinal cord. The sympathetic originates from the thoracic and lumbar spinal nerves.
What structures comprise the CNS?
The central nervous system (CNS) is comprised of the brain and the spinal cord. These structures are responsible for processing and transmitting information throughout the body, controlling various functions such as movement, sensation, and cognition.
