Chapter 1-6 Review: Cytology and Cell Structure (Fill-in-the-Blank)

Fill-in-the-blank flashcards covering nucleus structure, chromatin types, nucleolus, cell cycle phases, mitosis, cell types (static/stable), plane of section concept, histology stains (Nissl), leukocyte nuclear morphology, and Barr bodies based on the provided lecture notes.

The cell that does not have a nucleus in mammals is the __.

The nucleolus is the site for synthesis of __.

ribosomes

The two membranes of the nucleus are the inner membrane and the __ membrane.

outer

The space between the inner and outer nuclear membranes is called the __ space.

perinuclear

The longest phase of the cell cycle is the __ phase.

G1

Cells that do not divide reside in the __ phase (G0).

G0

During metaphase, chromosomes align at the __.

equator

In prophase, chromatin condenses into chromosomes and the nucleolus __.

In telophase, the nuclear envelope re-forms and the __ reappears.

nucleolus

Static cells include neurons and __.

cardiac muscle cells

Stable cells can re-enter the cell cycle after injury; an example is the __ cell.
