Name the various types of tissues and state their functions
Answers
There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
Epithelial tissue creates protective boundaries and is involved in the diffusion of ions and molecules.
Connective tissue underlies and supports other tissue types.
Muscle tissue contracts to initiate movement in the body.
Nervous tissue transmits and integrates information through the central and peripheral nervous systems.
Epithelial Tissue
Features - high cellularity, special sensory receptors, forms a barrier, avascular, innervated
Surfaces - basal (hemidesmosomes, basement membrane), apical (lumen, microvilli, cilia, stereocilia), lateral (adhering junctions, tight junctions, desmosomes, gap junctions)
Types - squamous, cuboidal, columnar, simple, stratified, pseudostratified, specialized
Connective Tissue
Structure - cells (structural, immunological, defense, energy reservoirs), extracellular matrix (ground substance, protein fibers)
Types of fibers - collagen, reticular, elastic
Classification - proper (dense, loose), embryonic (mesenchyme, mucous), specialized (cartilage, adipose, bone, blood)
Muscle Tissue
Features - elastic, extensible, contractile
Types - skeletal, cardiac (gap junctions, intercalated discs), smooth, striated, nonstriated
Nervous Tissue
Neurons - soma, dendrites, axons, ganglia (PNS), nuclei (CNS)
Glia - astrocytes, oligodendrocytes, Schwann cells, microglia - blood-brain barrier
Answer:
Connective tissues
Cardical tissues
Nervous tissues
Epithelial tissues
Explanation:
Connective.
1 .They are present in blood .
Cardical.
1 .It makes our muscles strong.
Nervous.
1 .
it work in inner parts of bodyourself
