Chapter #4 Anatomy Lecture

Where are cilia found?

Cilia are found in pseudostratified columnar.

Where are cilia found?

Cilia are found in pseudostratisfied columnar.

What is 25% collagen?

Collagen is the most prevalent protein in the connective tissue of animals and constitutes approximately 25% of total body protein in vertebrates.

What are membranes with parietal and visceral portions?

Membranes with parietal and visceral portions are the serous membrane.

What are serous membranes?

Serous membranes or serosa lines a body cavity that does not open directly to the exterior (thoracic or abdominal cavities), and it covers the organs that are within the cavity.

There are three types of epithelial tissue? What are the four cell types?

The three types of epithelial tissue are: apical (free) surface, lateral surface and the basal surface. The four cell types are: Squamous are flat, thin and cuboidal, cubed, columnar are much taller than they are wide and transitional.

What are the three types of muscle tissue?

The three types of muscle tissue are: skeletal, cardiac, and smooth. (Sammy can swim).

Where are microvilli found?

They are found mainly on the free cell surface. Hundreds of microvilli are found in absorptive cells, such as the lining epithelium of the small intestine. Small intestine increases the area and helps absorption.

Which tissue is most abundant?

connective tissue.

How does epithelial tissue function?

Epithelial tissue function by covering body surface and lining hollow organs, body cavities and ducts; they also form glands. This tissue allows the body to interact with both its internal and external environments.

What is keratin?

Keratin is a tough, fibrous intracellular protein that is found in the hair, skin and nails.

What are matrix of osseous tissue functions?

Osseous tissue or bone is the major structural and supportive connective tissue of the body. support - for muscles, organs, and soft tissues leverage and movement - the synovial joints protection - for critical organs calcium phosphate storage - mineral balance hemopoiesis - formation of blood cells

What are the 8 types of connective tissue?

The 8 types are: Embryonic mesenchyme and mucous ct, mature connective areolar, adipose tissue, reticular tissue, dense connective tissue, dense regular, irregular, elastic and fibroblasts, cartilage hyaline, bone, and blood.

What are the four types of tissue and their functions?

The four types of tissues are: epithelial covers body surfaces and lines hollow organs, cavities, and ducts; they also form glands. Connective tissue: This protects and supports the body and its organs. Muscular tissue: Are composed of cells specialized for contraction and generation of force. Nervous tissue: Detects changes in a variety of conditions inside and outside the body.

What is the function of the stratified squamous epithelium?

The function of the stratified squamous epithelium is a protection against abrasion, water loss and ultraviolet radiation, and foreign invasion.

What are endocrine glands?

Endo (inside) called hormones enter the interstitial fluid and then diffuse directly into the bloodstream without flowing through a duct.

What are exocrine glands?

Exocrine (outside) secrete products released into ducts that empty onto the surface of a covering and lining epithelium, such as skin surface or lumen of hollow organ.

What are fibroblasts a typical cell of?

Fibroblasts are a typical cell of dense CT.

Where are fibroblasts found?

Fibroblasts are found within fibrous connective tissue.

What is tissue repair or fibrosis?

Fibrosis (tissue repair) fibroblasts synthesize collagen and other extracellular matrix materials that aggregate to form scar tissue, a process known as fibrosis.

Where are goblet cells found?

Goblet cell a unicellular mucous gland found in the epithelium of various mucous membranes, especially that of the respiratory passages and intestines. Found in examples: stomach and small intestine.

What is the function of a goblet cell, what do they produce?

Goblet cells produce mucus.

What are lacunae?

Lacunae are small spaces between lamellae that contain mature bone cells called osteocytes. Lacuna (spaces) jelly-like matrix (chondroition sulfate) w/fibers and chondrocytes.

What are synovial membranes?

Synovial (together) membranes are referring to a place where bones come together and they line the cavities of freely movable joints.

What is the lamina propria?

The lamina propria is the CT layer of a mucous membrane. It is the connective tissue under the basement membrane layer of epithelium (mucous membrane).

What is the function of microvilli?

The main function of microvilli includes secretion, absorption, and cellular sticking or adhesion.
