What else can I help you with?
Does the decision-making function of the nervous system take place in the CNS?
Yes. The CNS is in the brain and spinal cord.
What Protect bone around the central nervous system?
the CNS is your brain and spinal cord, so the skull protects the brain, and the vertebrates in your spine help protect the nerves in your spine.
What nervous systems does the spine protect?
Central Nervous System (CNS)
What week can the cns be differentiated in developing embryo?
Week four
What cushions and protects the CNS?
The cerebrospinal fluid (CSF) acts as a cushion for the central nervous system (CNS), providing a protective layer around the brain and spinal cord. In addition, the meninges, which are the protective membranes that surround the brain and spinal cord, also help to cushion and protect the CNS from injury and infection.
What is the basic unit of CNS?
The basic unit of the central nervous system (CNS) is the neuron. Neurons are specialized cells that transmit electrical and chemical signals throughout the CNS, allowing for communication between different parts of the brain and spinal cord. Each neuron consists of a cell body, dendrites, and an axon, which together facilitate the processing and relay of information. Additionally, glial cells support and protect neurons, playing crucial roles in maintaining overall CNS function.
What are four things that protect the delicate brain?
There are three things that protect the CNS; brain and spinal cord. Bone which is the skull for the brain and the vertebrae for the spinal cord, meninges which is a protective membrane, and the spaces between the meninges are filled with cerebrospinal fluid for cushion and protection.
What type of neuroglial cell is not found in the CNS?
One type of neuroglial cell not found in the central nervous system (CNS) is the Schwann cell. Schwann cells are responsible for myelinating peripheral nerves in the peripheral nervous system (PNS). In contrast, oligodendrocytes serve a similar function in the CNS by myelinating axons. Thus, while Schwann cells are crucial for peripheral nerve function, they do not exist in the CNS.
Four types of neuroglia in the cns?
The four types in the CNS are microglia, astrocytes, ependymal, and oligodendrocytes. *microglia= phagocytes *astrocytes= form the blood brain barrier *ependymal= produce CSF (cerebral spinal fluid) *oligodendrocytes= form the myelin sheath that wraps around the axon
What is the smallest neuroglia of the cns?
The smallest neuroglia of the CNS is the microglia. They are small, specialized cells that act as the immune system of the brain, helping to protect and maintain the health of the neurons.
Dendrites function in the motor neuron?
To carry the nerve impulse from the CNS to the cell body
What are neurons entirely within the cns?
Interneurons are neurons entirely within the central nervous system (CNS). They function to relay signals between sensory neurons and motor neurons, allowing for complex processing and integration of information within the CNS.
