Tissues and Membranes


Tissues
Tissues

  • Tissues are groups of cells (four main types)

  • Epithelial tissue

  • Connective tissue

  • Muscle tissue

  • Nervous tissue

Edited by Dr. Ryan Lambert- Bellacov


Epithelial tissue 1 covering and lining
Epithelial Tissue1. Covering and Lining

  • Squamous epithelial cells

  • Cuboidal epithelial cells

  • Columnar epithelial cells


Epithelial tissue glandular and secretory
Epithelial TissueGlandular and Secretory

  • Endocrine gland cells

  • Exocrine gland cells


Animation exocrine and endocrine glands

Connective tissue 1 adipose fat
Connective Tissue 1. Adipose= Fat

  • Stores lipid

  • Acts as filler tissue

  • Cushions, supports, and insulates the body


Connective tissue areolar loose
Connective Tissue Areolar (Loose)

  • Elastin tissue

  • Collagen


Connective tissue 2 dense fibrous
Connective Tissue 2.Dense Fibrous

  • Ligaments

  • Tendons

  • Aponeuroses

  • Fasciae


Connective tissue supportive
Connective Tissue Supportive

  • Osseous (bone) tissue

  • Cartilage

    • Hyaline

    • Fibrocartilage

    • Elastic cartilage



Muscle tissue 3 types
Muscle Tissue (3 types)

  • Cardiac

  • Skeletal (striated voluntary)

  • Smooth (nonstriated involuntary)


Nervous tissue
Nervous Tissue

  • Conductivity


Effects of aging on tissue
Effects of Aging on Tissue

  • Cells become larger and less able to divide and reproduce

  • Increase in pigments and lipids inside cell

  • Waste products accumulate in the tissue

    • Cell membranes change and carbon dioxide and wastes have difficulty getting out

    • Many tissues lose mass and atrophy


Membranes
Membranes

  • Two thin layers of tissue together form a membrane

    Either

  • Epithelial membranes

  • Connective membranes


Epithelial membranes subdivided two
Epithelial Membranes- subdivided two

  • Mucous membranes leads to outside

    • Respiratory mucosa

    • Gastric mucosa

  • Serous membranes (parietal and visceral)

    • Pleural membrane

    • Pericardial membrane

    • Peritoneal membrane (abdominal)

    • Cutaneous membranes skin


    Connective membranes
    Connective Membranes

    • Synovial membrane

      • Two layers of connective tissue

  • Lines joint cavities

  • Secrete synovial fluid which prevents friction inside the joint cavity


  • Organs
    Organs

    • An organ is tissues grouped together to form a specific function

    • Organs coordinate their activities to form a complete functional organism

    • Organ system

      • Group of organs that act together to perform a specific, related function


    Organ systems
    Organ Systems

    • Skeletal

    • Muscular

    • Digestive

    • Respiratory

    • Circulatory


    Organ systems1
    Organ Systems

    • Excretory

    • Nervous

    • Endocrine

    • Reproductive

    • Integumentary


    Tissue and organ transplant
    Tissue and Organ Transplant

    • Blood transfusions are an example of a tissue transplant

    • All transplants (tissue and organs) must be cross-matched so recipient’s immune system won’t attack the donated organ

    • Rejection is main problem in organ transplants


    Disease and injury to tissue
    Disease and Injury to Tissue

    • Infection

    • Inflammation

    • Trauma

    • Abnormal growth of cells

    • Birth defects


    Tissue repair
    Tissue Repair

    • Primary repair clean wound

    • Secondary repair

      • Large tissue loss

      • Granulation occurs creating area for healing
