Chapter 5 tissues and bone Flashcards
Enzymes
A organic protein substance that initiates and accelerates chemical reactions in the metabolism
Tendons
band that attaches muscle to bone and consistes of tough collagen fibers
Aponeuroses
Wide flat sheet that connects muscle to muscle consists of tough collagen fibers
Ligaments
Band that connects bone to bone and consists of combination of collegen and elastin fibers
matrix
the material or tissue that surrounds and supports cells
Fascia
a thin layer of connective tissue that surrounds and supports muscles, bones, organs, and other body parts; supports, shape, and separate parts of the body
ATP Adenosine Triphosphate
Molecule that stores energy for muscular and other cellular activity
Endoderm
The innermost layer of cells the zygote
Mesoderm
Middle layer of cells in the zygote
Ectoderm
Outer most layer of cells in the zygote
Epithelial Tissues
Cover and protect the body
A protective layer on the outside and inside of the body that is responsible for absorption, excretion, secretion, and protection
ex: Skin, covering the inside and outside of organs
Types of Epithelial Tissues
*Simple Squamous (flat shape; 1 cell thick)
*Stratified Squamous (flat shape; Several cells thick but loosely compact)
*Transitional Squamous (flat shape; Several cells thick but tightly compact)
*Cuboidal (cube shape)
*Simple Columar (rectangle shape)
Epithelial membrane
Have their outer surface faced with epithelium; Mucous and Serous membrane
Mucous Membrane
(type of Epithelial membrane)
mucus substance produced to protects and lubractes cavities and canales that lead to the outside of the body
Serous Membrane
(type of Epithelial membrane)
Water substance produced to lubricate the close body cavities and the outermost surface of some organs in said cavities
pleural membrane
thin, double-layered sheet of tissue that covers the lungs and lines the inside of the chest cavity
Connective tissue membrane
a protective covering and make the movement of organs easier within the body
Skeletal membrane
Fibrous connective tissue membrane that covers and protects bone and cartilage; Periosteum and Perichondrium membrane
Periosteum Membrane
(connective tissue membrane)
Cover bone
Perichondrium Membrane
(connective tissue membrane)
Cover Cartilage
Muscle Tissues
Movement
Contractions causes movement; Skeletal, smooth, and cardiac muscle tissues
Skeletal muscle tissues/Striated muscle
Connected by bone or other muscle by way of tendons; Volentary movement responsible for movement of the body
Smooth muscle tissues/Non-striated muscles
connected to hollow organs; Involentary movement controlled by autonomic nervous system/glandular activity to move subsences throughout the body
ex: food, blood, urine
Cardiac muscle tissues
Found only in the heart; involentary and responsible for pumping blood through the heart
Nerve Tissues
Control and communitcate
made up of neurons(nerve cell) found in the brain spinal cord and associated nerves; receive stimuli, generate electrical impulses, and transmit those impulses throughout the body
Connective Tissues
Provides support
Binds structures together, provides support and protection, and serves as a framework; loose, dense, and specialized connective tissues
Loose connective tissue
Binds the skin to the underlaying tissues and fills the spaces between muscles
Areolar tissue
(Loose connective tissue)
Abundance of collagen and elastin fibers
Adipose tissue
(Loose connective tissue)
Tissue containing fat cells
Reticular tissues
(Loose connective tissue)
Provides framework of liver and other lymphoid organs
Dense connective tissues
Composed of collagen and fibers that are closely packed
Dense Regular connective tissues
Tendons, ligaments, and aponeuroses
Dense Irregular connective tissues
Muscle sheaths and joint capsules
Cartilage
protect and support bones, reduce friction, and act as a shock absorber; Fibrocartilage, Hyaline, Elastic
Fibro-cartilage
Characterized by collagenous fibers in the matrix
Hyaline cartilage
Fundamental type of cartilage consisting of fine white fibers
Elastic cartilage
Characterized by elastic fibers in the matrix
bone/ osseous tissue
connective tissue in which the intercellular substance is rendered hard due to mineral salts and callcium
Liquid connective tissues
blood, lymph, and interstitial fluid
