Located in the deepest layer of the epidermis they detect touch sensations by being incontact with the process neuron called a tactile or Merkel disc.5.Fill in the words or phrases that best complete each of the following sentences.a.Functions of the skeletal system include support, protection, assisting in movement,mineral homeostasis, blood cell production and triglyceride storage.b.The hollow space inside of long bones that is lined with endosteum and filled with yellowmarrow is the medullary cavity.c.The protein that provides flexibility and tensile strength to bone is collagen.d.Compact bone tissue is organized into concentric rings of bone tissue, which are calledosteons or haversian systems.e.Nerves accompany blood vessels within bone tissue; the periosteum is enriched withsensory neurons.f.Ossification may also be called osteogenesis; in an embryo, it begins with theorganization of mesenchyme tissue into the general shape of bones.g.Intramembranous ossification occurs between mesenchyme connective tissue sheet-likelayers that resemble membranes.h.Activity of the epiphyseal plate causes the diaphysis region of a bone to grow in length.i.Human growth hormone, IGFs, insulin and T3/T4are the primary stimulators of bonegrowth before puberty.j.Calcitonin is the hormone that inhibits the effects of parathyroid hormone.6.Match the items in column A with the descriptions in column B to create the BESTMATCHES.Assignment 1 ::Biology 235: Human Anatomy and Physiology5
