Tissues

Question 1

Tissue

Answer 1

aggregate of cells of same type with functional unity

Question 2

4 Tissue Types

Answer 2

Epithelial Tissue
Connective Tissue
Muscle Tissue
Nervous Tissue

Question 3

Epithelial Tissue

Answer 3

covering, superficial layer of mucous membranes and the cells constituting the skin, linings of major body cavities, all of the “tubes” that pass into, out of, and through the body,

Question 4

Connective Tissue Fibers

Answer 4

Reticular fibers: thin connective fibers​

Collagen fibers: strongest and most abundant fiber type; allow connective tissue to withstand tension (pulling forces)​

Elastic fibers : provide recoil to the tissue to spring back to its original shape

Question 5

Connective Tissue (proper)

Answer 5

Loose Connective Tissue
Areolar- helpful for supporting organs, supports and connects organs and other tissues, found below the epithelium, surrounding small nerves & blood vessels, and fills interstitial space between organs
Adipose- Areolar tissue with a high concentration of fat cells​, found just beneath the skin, between muscles, and between organs

Question 6

Dense/Fibrous Connective Tissue

Answer 6

Tendons, “Transmit the force generated by the contracting muscle to the bone” (Flyod, 2012) – Muscle to bone connection​ creates muscle to muscle connections AND muscle to ​
cartilage connections​

White fibrous (ligaments)- Strong, dense, and highly organized connective tissue, Binds structures together & is found in ligaments, which connect bone to bone, bone to ​cartilage, and cartilage to cartilage ​

Fascia- Sheet or band of fibrous connective tissue with matted fibers, Surrounds muscles and organs; provides isolation and stability​

Question 7

Cartilage- CT

Answer 7

strength and elasticity, Resistant to being separated when pulled, crushed when compressed

Hyaline Cartilage: provides surface for articulation of bone or other cartilage (i.e., trachea, larynx, bronchial passageway, cartilaginous portion of rib cage)

fibrocartilage : shock absorbing cartilage that acts as a cushion between bones (i.e., between vertebrae of the spinal column, temporomandibular joint)​

yellow (elastic) Cartilage: less collagen and more elastic fibers than other cartilage types (i.e., pinna (outer ear), nose, epiglottis)​

Question 8

Bone- CT

Answer 8

hardest connective tissue​, marrow produces red and white blood cells & blood plasma matrix

Question 9

Blood- CT

Answer 9

Fluid connective tissue, blood cells are formed in the marrow of bones​, blood cells (red blood cells, white blood cells, and platelets) are suspended in the plasma

Question 10

Connective Tissue cell types

Answer 10

fibroblasts - production of extracellular matrix- synthesize and secrete protein, wound repair​

microphages- collection of waste or dead (necrotic) tissue​

lymphocytes- defend against viral attacks and destroy viral agents​

Mast cells- inflammation for protection

Question 11

Muscle Tissue

Answer 11

Able to contract​

Types​

striated muscles or skeletal muscles: move the bones at the joints when contracted ​
(voluntary)​

smooth muscles: move blood in vessels and material down the digestive tract. (involuntary)​

cardiac muscles: muscles of the heart

Question 12

Nervous Tissue

Answer 12

Transmits information from:​

Neuron to neuron = interneuron​

Neuron to muscle = motor neuron​

Sensory receptors to other neural structures = sensory neuron
