Study Notes

Types of Tissue

Four main types of tissue: epithelial, connective, muscle, and nervous.
Epithelial tissue functions in protection, absorption, transport, and secretion; it covers surfaces and lines cavities.
Connective tissue provides support, binds organs, and integrates body systems; it includes various forms and membranes.
Muscle tissue enables movement through contraction; it consists of skeletal, smooth, and cardiac types.
Nervous tissue transmits signals as electrochemical impulses, facilitating communication within the body.

Tissue Differentiation

Differentiation is the process where less specialized cells mature into specialized types.
Cells in developing embryos originate from three primary germ layers: ectoderm, mesoderm, and endoderm.
The zygote is totipotent, forming all body cells, including specialized cells like neurons through differentiation stages.

Embryonic Germ Layers

Ectoderm: Outermost layer; develops into epidermis and nervous tissue.
Mesoderm: Middle layer; forms connective tissues, muscle tissues, and some epithelial tissues.
Endoderm: Innermost layer; gives rise to most of the digestive and lower respiratory systems.

Types of Membranes

Mucous membranes: Line cavities exposed to the external environment and are protected by mucus.
Synovial membranes: Connective tissue that supports joint mobility and produces lubricating synovial fluid.
Serous membranes: Line body cavities and are lubricated with serous fluid to reduce friction.
Cutaneous membrane: The skin, composed of stratified squamous epithelial cells.

Histology

Histology is the microscopic study of tissue architecture and organization, crucial for understanding tissue function and pathology.

Cell Types and Functions

Fibroblasts in connective tissue membranes produce hyaluronan, essential for synovial fluid production, enhancing joint movement.
Connective tissue membranes encapsulate organs and line movable joints, providing structural support.

Totipotent Cells

Totipotent cells can differentiate into any cell type, enabling the formation of all tissues and organs during development.
