Simple Columnar
Location | Intestinal tract |
Simple Columnar
Function | Absorption, secretion of mucus, enzymes, and other substances |
Pseudostratified Ciliated Columnar
Location | Trachea and bronchial tubes |
Pseudostratified Ciliated Columnar
Function | Secretion of mucus, propulsion of mucus by cilia |
Stratified Squamous
Location | Lines mouth,vagina, esophagus, skin |
Stratified Squamous
Function | Protection |
Specific types of stratified squamous | Keratinized
Non-keratinized |
Major types of adult tissues | Epithelial
Connective
Muscle
Nervous |
Main classes of connective tissue | Connective tissue proper (Fibrous Tissue)
Cartilage
Bone tissue
Blood |
Functions of connective tissue | Enclose organs-Areolar
Connect tissues to one another-Tendons and ligaments (Dense connective tissue)
Support and movement-Bone
Storage-Fat
Insulation-Fat
Transport-Blood
Protection-Bones, cells of the immune system |
Fibroblasts | secrete the protein needed for fiber synthesis and components of the extracellular matris |
Adipose (adipocytes) | Common in some tissues (dermis of skin); rare in some cartilage |
Mast Cells | Common beneath membranes; along small blood vessels. can release heparin, histamine, and proteolytic enzymes in response to injury |
Leukocytes | Respond to injury or infection |
Macrophages | Derived from monocytes (a WBC). Phagocytic; provide protection |
Chondroblasts | Form cartilage |
hematopoietic stem cells | form blood cells |
undifferentiated mesenchyme (stem cells) | have potential to differentiate into adult cell types |
The 3 major components of ECM | 1.Protein fibers(Collagen, Elastic, Reticular)
2.Ground substance
3.Fluid |
Collagen Fibers | Composed of the protein collagen. strong, flexible, inelastic; great tensile strength. Perfect for tendons, ligaments |
Elastic Fibers | Contain molecules of protein elastin that resemble coiled springs. Returns to its original shape after stretching or compression. Perfect for lungs, large blood vessels |
Reticular Fibers | Formed from fine collagenous fibers; form branching networks (stroma). fill spaces between tissues and organs. |
Adipose Tissue
Function | Protection, storage |
Adipose tissue
Location | Under the skin, around the eyes kidneys, heart |
Reticular (Loose) Connective Tissue
Location | Internal skeleton: lymph nodes, spleen |
Reticular (Loose) Connective Tissue
Function | Soft internal skeleton, supports other cell types. |
Hyaline
Function | support, reinforce, resist compressive stress |
Hyaline
Location | Embryonic skeleton, cover end of bones, trachea, nose, larynx |
Aerolar Loose Connective
Function | Wraps and cushions organs; inflammation |
Aerolar Loose Connective
Loction | Widely distributed under epithelia |
Dense connective Tissue
Location | Tendons, ligaments, aponeurosis |
Dense connective Tissue
Function | Attaches muscles to bones and bones to bones |
Osseous Tissue
Function | Storage, support |
Osseous Tissue (Compact)
Location | Bones |
Spongy Bone or Cancellous Bone
function | Support |
Spongy Bone or Cancellous Bone
Location | In the center of flat bones and in the ends of long bones |
Types of blood cells | Erythrocytes-RBC
Leukocytes-WBC
Thrombocytes-Platlettes |
Characteristics of muscle tissue | -cells are referred to as fibers
-contracts or shortens w/force when stimulated
-moves entire body and pumps blood |
Types of Muscle tissue | Skeletal-attaches to bones
Cardiac-muscle of the heart
Smooth-muscle associated w/tubular structures and with the skin. nonstriated and involuntary |
Skeletal Muscles
Function | Voluntary movement
locomotion
manipulation of the environment
facial expression
voluntary control |
Skeletal Muscles
Location | muscles attached to bones or occasionally to skin |
Cardiac Muscles
Location | The walls of the heart |
Cardiac Muscles
Funtion | As it contracts, it propels blood into the circulation
involuntary control |
Smooth Muscle
Function | Propels substances or objects along internal passageways (foodstuff, urine, baby) |
Smooth Muscle
Location | Mostly in the walls of hollow organs |
Nervous Tissue
function | transmit electrical signals from sensory receptor and to effectors (muscles and glands) that control their activity |
Nervous Tissue
Location | Brain, spinal cord, and nerves |
Layers of the Epidermis | Stratum Corneum
Stratum Lucidum
Stratum Granulosum
Stratum Spinosum
Stratum Basale |
