False, antibiotics help most with bacterial infections.
Numerous antiepileptic medications, such phenytoin, have been designed to block voltage-gated sodium channels (VGSC) in neuronal membrane. In addition, multiple toxins and pharmacological modulators work by attaching to various biophysical states of the VGSC to cause their effects. Depending on how modulatory agents act, some VGSC states are stabilized or destabilized, altering the channel's biophysical properties. The first anticonvulsant to successfully treat epileptic disorders without causing undesirable side effects such as brain drowsiness was phenytoin.
Phenytoin has been indicated to block high-frequency neuronal activity potentials from the inner vestibule of the pore, as demonstrated by electrophysiological research and site-directed mutation.
Frequency and voltage both affect phenytoin binding.
There are theories that phenytoin interferes with the late sodium current that sustains depolarizations in epilepsy by blocking non-inactivated channels.

The anterior and the posterior fontanelles is made up of the MESENCHYMAL CONNECTIVE TISSUES.
The anterior and the posterior fontanelles are two areas that are normally found on infant heads; at these areas, the skull bones did not cover the brain completely. The anterior fontanelles is located towards the front of the head while the posterior fontanelles is located at the back of the head. As the baby grow older, the mesenchmal tissues of the fontanelles turns into bone tissues.
Radius and Ulna.
Those are the long bones that together form the forearm.
The external bone is the radius, and the inside bone is the ulna, they are joint by its extremes.
The humerus is the bone that forms the arm.
Carpus is a conjunction of bones that form the wrist.
