-
Squamous Epithelium
- Class: simple epithelial
- description: single layer of flat cells
- where: blood vessels, heart, alveoli, lymphatic vessels
-
Cuboidal Epithelium
- class: simple epithelial
- description: cubed shaped
- where: secretory function on glands and the thyroid
-
Columnar Epithelium
- class: simple epithelial
- description: singal layered, cylindrical
- where: lining of the stomach, intestines, galbladder, bile ducts
-
Ciliated Epitelium
- class: simple epithelial
- description: cylindrical and with hair
- where: nasal cavity, larynx, trachea, bronchi
-
Stratified Epithelium
- class: compound epithelial
- description: flattened cells on bed of columnar cells
- where: epidermis of skin, lining of mouth, pharynx, esophagus, conjunctiva
-
Transitional Epithelium
- class: compound epithelium
- description: pear shaped
- where: lining of the bladder
-
Basement Membrane
- class: epithelium
- description: made of collagen, underlies epithelial tissue
- function: stabilizes and joins together epithilial and connective tissues
-
Areolar Tissue
- class: connective tissue
- description: elastic
- where: supports organs between muscles
-
Adipose Tissue
- class: connective tissue
- description: cells w/fat globules
- where: between muscles and organs
-
White Fibrous Tissue
- class: connective tissue
- description:
-
White Fibrous Tissue
- class: connective tissue
- description: strong, closely packed
- where: ligaments binding bones, periosteum covering bone, covering organs, fascia over muscle
-
Yellow Elastic Tissue
- class: connective tissue
- description: elastic, recoil
- where: in area requiring recoil such as the trachea, cartilage, bronchi, lung
-
Lymphoid Tissue
- class: connective tissue
- description: lymphocytes
- where: tonsils, adenoids, lymphatic nodes
-
Hyaline Cartilage
- class: cartilage; connective tissue
- description: bluish white, smooth, firm, flexible
- where: articulating surfaces of bone, costal cartilage of ribs, larynx, trachea, bronchial passageways
-
Fibro Cartilage
- tissue: cartilage; connective tissue
- description: dense,white flexible fibers
- where: intervertebral disks, between surfaces of the knee joint (synovial fluid)
-
Yellow ( elastic) Cartilage
- class: cartilage;connective tissue
- description: firm elastic
- where: pinna, epiglottis
-
Blood Tissue
- class: connective tissue
- description/where: corpuscles (red and white), platelets, blood plasma
-
Compact Bone Tissue
- class: hardest connective tissue
- description/where: haversian canal, lamellar structure
-
Cancellous (spongy) Bone Tissue
- class: hardest connective tissue
- description: spongyin appearance
- where: larger haversian canal, red marrow
- purpose: produces red & white blood cells and plasma
-
Striated (Skeletal)Tissue
- class: muscular tissue
- description: voluntary
- where: skeletal system
-
Smooth Tissue
- class: Muscular tissue
- description: involuntary
- where: muscles of internal organs
-
Cardiac Tissue
- class: Muscular Tissue
- description:involuntary; combo of smooth and striated
- where: heart
-
Neurons
- class:Nervous Tissue
- description: transfer info
- where: communicating tissue
-
Glial Cells
- class: Nervous Tissue
- description: nutrient transfer
- where: blood-brain barrier
-
Tissue Aggregate
Fascia, Ligaments, Tendons, bones, joints. e.g. Tissues of a muscle/organ that all serve the same general purpose (functional utility)
-
Fascia
sheet like membrane that surrounds organs
-
Ligaments
bind organs together or hold bone to bone or bone to cartilage
-
Tendons
attach muscle to bone or cartilage; if flat: aponeurosis
-
Bones/cartilage
provide the structure for the body; articulating by means of joints
