Unit 1
Four major tissues types
Epithelial tissue (ET)
Connective tissue (CT)
Muscle tissue (MT)
Nervous tissue
Connective Tissue characteristics?
not tightly packed, surrounded by extracellular matrix (ECM) (also called intercellular matrix)
•epidermis and dermis make up the?
Skin/Integument/cutaneous membrane
Which layer is damaged in first degree of burn?
epidermis
Skin Cancer types?
Squamous cell carcinoma
Basal cell carcinoma
Malignant melanoma
Kaposi sarcoma (KS) (HHV8)
Epithelial Tissue characteristic?
tightly packed cells, arranged in layers.
Alternate names of skin?
Integument and cutaneous membranes
Skin consists of ------------Layers?
2
What do we determine by ABCDE rule?
To determine Malignant melanoma / Skin cancer
Warning Signs of Malignant Melanoma
Asymmetry
Border
Color
Diameter
Evolving
Simple vs Stratified Epithelial Tissues?
Simple (single layer of cells of the same shape)
Stratified (many layers of cells).
Serous membrane types?
•Parietal layer: Line walls of body cavities
•Visceral layer: Cover organs found in body cavities
Hypodermis consists mostly of?
Adipose tissues/fat tissues
Accessory Organs of the Skin?
Hair
Nails
Skin receptors
Classification of Burns
First-degree (partial thickness) burns
Second-degree (partial thickness) burns
Third-degree (full thickness) burns
Fourth degree (full thickness) burns
Classification of epithelial tissues according to shape?
Squamous
Cuboidal
Columnar
Transitional
Pseudostratified
3 types of Epithelial Membranes?
Cutaneous membrane
Serous membranes
Mucous membranes
Which layer of skin contains blood vessels and nerve fibers?
Dermis
Where are Sebaceous glands located?
near hair follicles secretes sebum
Most common type of skin cancer
Basal cell carcinoma
Exocrine Glands vs Endocrine Glands
secrete their secretion through a duct.
Ductless, secrete their secretion directly into the blood by diffusion.
Connective Tissue Membranes
Synovial membranes, lining the joint capsule
Which layer of the skin is closest to the surface?
Stratum Corneum
Functions of skin?
Protection
Temperature regulation
Sense organ activity
Synthesis of vitamin D
Most serious form of skin cancer
Malignant Melanoma
