Transverse This body cavity includes the cranial and spinal cavities. dorsal This body cavity includes the orbits & the nasal, oral, thoracic & abdominopelvic cavities. Ventral Study of tissues histology Group of cells that act together to perform specific functions. Tissue The 4 fundamental tissues epithelial, connective,muscle & nerve Tissue that covers, lines & protects the body and its internal organs epithelial tissue ACTUAL QUESTIONS WITH CORRECT VERIFIED Tissue that is the framework of the body, providing support & structure for the organs. Tissue composed of neurons & connective tissue cells that are called neuralgia Tissue that has the ability to contract or shorten; it is classified as voluntary or involuntary. connective tissue nerve tissue muscle tissue voluntary muscle tissue skeletal muscle tissue Involuntary muscle tissue smooth muscle & cardiac muscle tissue ______ include the enzymes that regulate all chemical reactions in the body. proteins Where does meiosis take place? gonads Mucous, serous, synovial & cutaneous are membranes composed mainly of ______ tissue What is replaced by bone during embryonic development? ______ is mainly found in joints, thorax & various rigid tubules.
