Cerebral spinal fluid
connective
The central nervous system (CNS) is protected by the skull and vertebral column, which provide physical protection. Additionally, the meninges - a set of membranes - cover the brain and spinal cord, providing cushioning and support. Blood-brain barrier, formed by specialized cells lining blood vessels in the brain, regulates what substances can enter the CNS, protecting it from harmful agents.
Cerebrospinal fluid provides insulation to the human brain. It acts as a shock absorber that cushions the brain and protects it from impact during movement.
axons
Afferent neurons receive and transmit impulses to the CNS.
The membrane that surrounds the embryo and is filled with fluids that cushions and protects the embryo is called the amniotic sac or amnion.
connective
The amniotic sac is the structure that protects and cushions the embryo during pregnancy. It is filled with amniotic fluid that helps absorb shocks and regulate temperature for the developing fetus.

cerebral spinal fluid cushions, protects and nourishes the brain and spinal cord.
The human central nervous system (CNS), which includes the brain and spinal cord, is protected by several structures. The bony skull and vertebral column provide a hard protective barrier, while the meninges—three layers of membranes—envelop the CNS. Additionally, cerebrospinal fluid (CSF) cushions the brain and spinal cord, helping to absorb shocks and maintain a stable environment for neural function. Together, these protective mechanisms safeguard the CNS from injury and disease.
The hedgehog and the porcupine, are two animals that have protective quills.
