Introduction

Phrenology

Phrenology

[________ is the detailed study of the shape and size of the cranium (skull) based on the former belief that they are indicative of mental faculties and character]

Tiny dendritic spines

________ have neural plasticity- their number and structure are rapidly altered by experience.

myelin sheaths

It is white because the ________ (which are white fatty tissues) cover the axons.

Oligodendrocytes

________ and Schwann cells wrap around successive segments of axons to insulate them with fatty substance called myelin.

II

The optic (________) nerves carry visual information from the eyes.

caudate nucleus

[The ________ is a paired "C "shaped subcortical structure which lies deep inside the brain near the thalamus]

Ependymal Cells Line

________ ventricles secrete and absorb cerebrospinal fluid.

IX

The glossopharyngeal (________) nerves receive additional taste sensations and sensations from the throat and also control the muscles there.

SER

________- smooth endoplasmic reticulum regulates cytoplasm.

cell body

In multipolar and bipolar neurons the ________ also receives synaptic inputs (which makes it also a part of the input zone)

Phrenologists

________ are people who believed that the development of specific intellectual traits was associated with brain growth that literally made the skull overlying that part of the brain bulge out.

synaptic cleft

The ________ (a gap of 20- 40 nanometer) that separated the presynaptic and postsynaptic neurons.

Nissls stains

________ can help distinguish between neurons and glia as well as identify the arrangement of neurons.

light odor

This is the neurons that responds to environment such as ________ or touch.

Cytoarchitecture

[________ is the study of the structural arrangement of neurons within the central nervous system (neuronal size, shape, packing, density, and staining intensity are all features that are used to characterize a specific cytoarchitectural area region or trend]

neuron

The ________ has three parts: dendrite, soma (cell body) and axon.

Cresyl Violet

[________: a basic dye and is used as a common stain in histology]

oculomotor

The ________ (III) Trochlear (IV) Abducens (VI) nerves innervate muscles to move the eyes.

hypoglossal

The ________ (XII) nerves control the tongue.

VIII

The vestibulocochlear (________) nerves convey information about hearing and balance.

Golgi

________ stains allow a view of only occasional cells.

spinal cord

Each nerve is made up of motor fibers- projecting from the ventral (front) of the ________ to the organs and muscles.

Glial cells

________ support the brain.
