tissue test review

Secreation of holocrine.

entire cell ruptures, releasing secreations, and dead cell fragments.

secreation of merocrine

glands secrete their

products by exocytosis. (sweat, pancreas)

secretion apocrine

• accumulate products within, but only apex ruptures; whether this type exists in humans is controversial (maybe mammary cells?)

1. What type of epithelia are goblet cells found?

Simple columnar and pseudo-stratified columnar (COLUMNAR)

1. Where do you find intercalated disc? 

cardiac

1. What type of loose connective tissue would you find macrophages? Know all of them.

Areolar, adipose, and reticular

White fat

• Similar to areolar tissue but greater nutrient___ storage

• Cells are called __adipocytes_

Brown Fat

Use lipid fuels to heat bloodstream

Where do you find Hyaline cartilage

• Found at tips of long bones, nose, trachea, larynx, and cartilage of the ribs

Where do you find Elastic cartilage?

• Found in ears and epiglottis

Where do you find Fibrocartiliage

• Strong, so found in areas such as _____intervertebal____ discs and knee

poor regnerative

muscle and nervous

moderate regenerative

smooth, dense reg CT

good regenerative

epithelial , blood, areoler CT, dense irreg, bone

ex of CT

loose- areoler, adipose, reticuler Dense- reg, irreg, elastic

whats in bone

Osteoblasts

Fibroblast

found in connective tissue

chondroblast

found in cartiliage

microvilli

• some have specialized fingerlike projections called increase abosption

cilia

tiny, hair-like structures that stick out from the surface

1. What connective tissue structural elements make up the extracellular matrix?

Protein fibers, and brown substance

Loco Simple Squamous epithelium

a single layer thin,Air sacs of the lungs (alveoli), capillary walls, lining of blood and lymphatic vessels (endothelium), and serous membranes lining body cavities, allows diffusion

Loco simple cuboidal epithelium

Kidney tubules, secretory ducts of small glands, thyroid follicles, and pancreas.

Simple columnar epithelium

Non-ciliated lines most of the digestive tract (stomach to rectum); ciliated lines small bronchi, uterine tubes, and the uterus

Loco pseudostratified epithelium

Lining of the trachea and most of the upper respiratory tract.

1. What type of cells will you see in areolar connective tissue? 

fibroblasts, macrophages, fat cells, and white blood cells.

1. What is a big function of epithelial tissue? Be able to make a connection to body function.

Protection, absorption, filtration, excretion.

1. Know the fiber types in connective tissue and the characteristics of each.

collagen fibers, elastic fibers, and reticular fibers

1. Define tissues and histology.

A tissue is a group of similar cells and their surrounding material that work together to do a specific job, and histology is the microscopic scientific study of those tissue structures

1. Know the difference between endocrine and exocrine glands. 

endocrine secretes directly internally into the body. Exocrine released into the body surfaces/cavities.

tissue repair

• regenerate, fibrosis

1. Know the main components of CT.

Ground substance fibers and cells.

1. Know the main job of connective tissue.  

Protecting insulating transporting.

find CARDIAC

The walls of the heart, specifically forming the middle layer known as the myocardium.

find smooth muscle

the walls of hollow internal organs and structures. (digestive)

find skeletal

Attached to bones across the skeleton.

1. Know the different types of membranes

cutaneous, mucous, serous

cutaneous

(the skin)

covers the body surface.

mucous

line body

cavities that are open to the

exterior.

Serous

line body cavities

that are closed to the exterior.

1. What is mesenchyme?

The organ of all connective tissue.

1. What is keratinized stratified squamous epithelium?

is a tough, waterproof tissue type made of multiple layers of flat cells filled with the protective protein keratin found in SKIN.

1. Types of primary tissue.

epithelial, connective, muscle, and nervous tissue

Simple Tubular

Simple Branched Tubular

1. What makes up myofilaments?

Actin, mycin.

1. Membrane linings and coverings are composed of what two tissues?

Epithelial and Connective tissues.

Basal

 lower attached side, faces inwards toward body

Apical

upper free side, is exposed to surface or cavity

is CARDIAC involuntary or vol

involuntary

smooth muscle invol or vol

invol

skeletal

vol

find mesothelium

 in the ventral body cavity

1. endothelium?

lining of lymphatic vessels, blood vessels, and heart.

PRIMARY GERM LAYERS:

ECTODERM; MESODERM; nervous tissues come from ectoderm. Muscle/connectives come from mesoderm. Epithelia comes from endoderm, mesoderm, and ectoderm.

Location of fibrocartilage

the intervertebral discs of the spine and the menisci of the knee.
