Smallest living unit organization in the body is the ____ because is capable of performing any necessary functions w/o the aid of other cells.

a group of cells with similar characteristics of form and function together form a

a tissue is a collection of similarly specialized cells that will then form into

Tissue types are categorized to four basic histologic types:

During prenatal development that embryonic cell layers differentiate into various basic embryologic tissue types:

______ time it takes for newly divided cells to be completely replaced throughout tissue

______ varies from tissue to tissue as well as between specific regions within tissue

_____is the tissue that covers and lines both the external and internal body surfaces, including vessels and small cavities.

_____ serves as protective covering, tissue absorption, secretion, sensory, protects more complex inner structures from physical, chemical, ad pathogenic attack and dehydration and heat

_____ consist of closely grouped polyhedral cells surrounded by very little or no intercellular substance or tissue fluid

________ are usually tightly joined to each another by intercellular junctions provided for by the desmosomes

_______ is located between most epithelium and deeper connective tissue

_____ is single layer of epithelial cells

most epithelium in the body consist of ____, it can be nonkeratinized or keratinized

_____  found within the keratinized tissue is tough, fibrous, opaque, waterproof protein that is impervious to pathogenic invasion

____ is time needed for a cell to divide during mitosis and pass through the entire thickness of tissue

The _____ turnover time is a result of the higher level of mitosis in those deepest dividing cells near the basement membrane

The ______ that lines the cheek tissue has a faster turnover time (14 days) than the epithelium that covers the skin

superficial layer of the basement membrane is the ______ which is produce by epithelium

the deeper layer of the basement membrane is the _____ which consist of collagen fibers and reticular fibers

_____ is the most abundant type of basic tissue in the body which is derived from somites.. functions are support, attachment, packing, insulation, storage, repair, defense

Most connective tissue is renewable because its cells are capable of

in most cases connective tissue is ____(except cartlage) each having its own blood supply.

the most common cell in all types of connective tissue is the

the main connective tissue fiber type found in the body is

tissue containing a large amount of collagen fibers is considered a

Type I collagen include____ and _____

The _____ are another type of fiber, composed of microfilaments embedded in the protein elastin, its ability is to stretch

After a clot forms and an inflammatory response is triggered with WBCs, fibroblasts migrate to produce an immature connective tissue deep to the clot and newly forming epithelial surface.This immature connective tissue is considered ___ which has few fibers and an increased number of blood vessels.

____ forms most of the temporary skeleton of the embryo and then serves as structural support for certain tissues after birth.

connective tissue surrounding most cartilage is ______ which contains blood vessels

____ produce cartilage matrix

_____ mature chondroblasts that maintain the cartilage matrix

_____ is small space that surrounds the chondrocyte within the cartilage matrix

____ is the most common type found in the body and contains only collagen fibers as part of its matrix

rigid form connective tissue that constitutes most of the mature skeleton is the

_____ aids in movement, manufactures blood cells,

outer part of the bone is covered with

deepp to the periosteum is a dense layer called

deep to the compact bone is a spongy layer called

_____ lines the medullary cavity bone on the inside of the layers of compact bone and cancellous bone

on the innermost part of the bone in the medullary cavity is the

Bone consist of cells and a partially mineralized matrix that is 60% inorganic or mineralized material and the inorganic substance is crystalline formation of mainly

bone matrix is initially formed as

bone matrix in compact bone is formed into closely apposed sheets called

highly organized arrangements of concentric lamellae in compact bone is the

____ is the unit of structure in compact bone and consist of 5 to 20 lamellae.

the _______ is a central vascular canal within each osteon surrounded by lamellae

______ is formation of osteoid between two dense connective tissue sheets(maxilla and mandible are formed by this)

______ is the formation of the osteoid within a hyaline cartilage model (most long bones are formed this way also the mandibular condyle)

____ is a fluid connective tissue that serves as transport medium for cellular nutrients, such as respiratory gases like oxygen and carbon dioxide

_____ is the fluid substance in the blood vessels that carries the plasma proteins, blood cells, and metabolites.

_________ transports the oxygen and carbon dioxide (no nucleus)

__________function in the clotting mechanism.

In even smaller numbers in the blood is the ______. are involved in the defense mechanisms of the body, including the inflammatory and immune responses. (nucleus)

The most common WBC in the blood is the

The second most common WBC in the blood is the_____, which makes up 25% to 33% of the WBC count.
There are three functional types:

Once mature, plasma cells produce an _____, one of the blood proteins.

The 3 types of muscle are classified according to structure, function, and innervation:

_____ forms the nervous system in the body; it is derived from the neuroectoderm within the embryo.

A _____ is the functional cellular component of the nervous system and is composed of three parts: one neural cell body with two types of neural cytoplasmic processes.

a______ impulses away from the cell body

A ____ is a bundle of neural processes outside the central nervous system and in the peripheral nervous system

A _____ is the junction between two neurons or between a neuron and an effector organ

An _____ or sensory nerve, carries information or relays impulses from the periphery of the body to the brain (or spinal cord).

An _____ or motor nerve, carries information away from the brain to the periphery of the body.

The ______is involved in fight‑or‑flight responses, such as in the inhibition of salivary gland secretion (hyposalivation

The _______ is involved in rest‑or‑digest responses, such as the stimulation of salivary gland secretion.
