Astrocytes perform the function of all of the given options i.e., induce the formation of the blood-brain barrier, physically support neurons, are important in the repair of brain injuries and in neural formation, take up excess K from the brain ECF.
- Both invertebrates and vertebrates have Astrocytes, a star-shaped cell kind of neuroglia, in their nervous systems.
- Astrocytes can be separated into protoplasmic and fibrous kinds. In the central nervous system's white matter, myelinated nerve fibers are frequently surrounded by fibrous astrocytes.
- Numerous cytoplasmic processes on astrocytes end on axons, neuronal cell bodies, blood vessels, and synaptic terminals.
b) The development of the blood-brain barrier is aided by the Astrocytes
c) Astrocytes support neurons physically and metabolically.
d) Astrocytes help in transfer of blood-borne materials to the neuron, and injury response of the brain and repair of brain injuries.
e) They also help with detoxification, migratory guidance, energy metabolism regulation and removal of excess K from brain ECF.

The function of the joint capsule ( articular capsule ) is to produce synovial fluid.
The joint pill presents passive joint stability, proscribing the joint range of motion, mostly via the tough, fibrous outer layer. The capsule also affords nutrients and lubrication to the joint via the internal synovial layer.
The articular capsule additionally includes two layers
- The outer fibrous membrane which could incorporate ligaments and
- The internal synovial membrane that secretes the lubricating, shock-soaking up, and joint-nourishing synovial fluid.
The joint pill, ligaments, and tendons serve to stabilize the joint, distribute the biomechanical load at the joint and shield the joint through proscribing its regular variety of movement.
It includes two layers, an outer fibrous layer and an inner layer known as the synovial membrane. also called the synovium, it includes a synovial lining and the assisting stromal tissue. It produces synovial fluid that lubricates the joint. The fibrous outer layer of the articular tablet improves joint balance.

<span>The cell would not survive if it gets exposed to drug which disables the transport proteins in the cell membrane. Due to this the supply of nutrients is not received by the cell and the cell is not capable of producing the molecules that are needed for the growth.</span>
