Tissues are an intermediate level of organization between cells and organs.  Objectives Objectives : After completing this worksheet, the student will be able to: Identify the four primary tissues in the body and the subcategories. Identify tissue subcategories through microscopic inspection of a prepared slide and through diagrams. Describe the functions of the different tissue types List specific areas in the body where the different tissue types can be found.  Primary Tissue Primary tissue refers to the fundamental Type of Primary Tissues types of tissues that Epithelial tissue form the basis of all Connective tissue other tissues in the Muscle Tissue Nervous Tissue body. Epithelial tissue Epithelial tissue  Function of Epithelial tissue Epithelial tissue performs several key functions: Protection: Acts as a barrier against physical, chemical, and biological damage. Secretion: Releases substances like mucous, enzymes, and hormones. Absorption: Facilitates the uptake of nutrients and water. Sensation: Houses sensory receptors for sensory perception.  Connective tissue Connective Tissue is one of the four primary types of animal tissue, playing a crucial role in supporting, connecting, and protecting other tissues and organs in the body. It consists of cells embedded in an extracellular matrix composed of ground substance and protein fibers like collagen, elastic, and reticular fibers Connective tissue  Connective tissue function Support and Structure: Provides framework for the body through bones and cartilage. Protection: Safeguards organs with fibrous capsules and bones. Transportation: Facilitates movement of nutrients, waste, and immune cells via blood and lymph. Energy Storage: Adipose tissue stores fat for energy. Immune Defense: Specialized cells defend against pathogens. Tissue Repair: Helps in healing damaged tissues. Muscle tissue  Nervous tissue Nervous tissue is the primary component of the nervous system, consisting of neurons and neuroglia. Neurons transmit electrical signals, while neuroglia support and protect neurons  Nervous tissue Function of Nervous Tissue The main functions of nervous tissue include: Communication: Conducting electrical signals across the body to facilitate communication between different parts. Sensory Input: Interpreting environmental stimuli through sensory neurons. Control of Muscles and Glands: Regulating muscle contraction and glandular secretion. Homeostasis: Maintaining internal balance by monitoring and adjusting body conditions Conclusion Thank You
