Oral histology and embryology Elsevier Qs chapter 1

C. Mobile cilia

Which cellular component has a site-specific function?

A) nucleus

B) cytoplasm

C) mobile cilia

D) plasma membrane

Intercellular material.

Surrounding each cell is the ———————— ———————. It provides the cell with nutrition, takes up waste products, and provides the body with form. It may be as soft as loose connective tissue, or as hard as cartilage, bone, or teeth.

Messenger RNA

Genetic information is carried by:

Golgi apparatus

This organelle sorts, condenses, packages, and delivers proteins.

Rough ER

The ————— —— is the sight where production of proteins is initiated. Each type of protein is composed of a number of different amino acids linked in a specific sequence. Amino acids form protein-containing groups, which form acids and bases.

B. Lysosome

Which intercellular component facilitates phagocytosis?

A) centriole

B) lysosome

C) ribosome

D) mitochondrion

Neuroblasts

——————— are primitive brain cells.

The fertilization of the egg.

The origin of tissue begins with what?

Meiosis

The reduction of chromosomes in the daughter cell of an ovum or spermatozoon. This process is describing:

Metaphase

In which phase of mitosis are the chromatids split into 2 sets of chromosomes?

Pulp

Stem cells can be found in what dental tissue?

Embryonic

During which period of growth is the developing human most susceptible to teratogens?

Endochondral ossification

———————— ——————— is the process by which bone replaces cartilage.

Intramembranous ossification

The majority of flat bones of the head and face develop through what process?

Mesoderm

Skin, hair, and nails arise from the ectoderm. Muscles, connective tissue derivatives such as bone, cartilage, blood, dentin, pulp, cementum, and the periodontal ligament all arise from the:

Lysosome

These are small, membrane bound bodies that contain digestive enzymes to help break down substances both inside and outside the cell.

Prophase

The chromatin thread of the nucleus thickens into rod like structures called chromosomes during which stage of mitosis? PMAT!
