Expert Solution

muscles that move the eyeball are superior and inferior obliques.

Answer - superior and inferior obliques

There are a total of 6 muscles needed to move our eyeball

Superior obliques
Inferior obliques
superior rectus
Inferior rectus
Medial rectus
Lateral rectus

The central nervous system is the source of thoughts and emotions and it excludes the cranial and spinal nerves, ganglia, and sensory receptors.

Answer - d. A and B are correct.

cranial and spinal nerves, ganglia, and sensory receptors are part of the Peripheral nervous system(PNS).

Thoughts and emotions drivers from the brain which is part of the Central nervous system.

oligodendrocytes, Schwann cells, and satellite cells are neuroglia cells that produce myelin.

Answer - e. A, B and C are correct.

an oligodendrocyte is a neuroglia of Central nervous system (CNS)

Schwann cells and satellite cells are the neuroglia of the Peripheral nervous system (PNS)

Neuroglia is the nonneural cells of the Nervous system that does not produce impulses but they support, protect and noursh nurons.
