The responses of muscle spindles in sheep extraocular muscles.

Number and distribution of neuromuscular spindles in human extraocular muscles.

PURPOSE To examine the number and distribution of muscle spindles in all extraocular muscles (EOMs) in humans. METHODS Thirty-six EOMs were obtained after death from three persons 67, 72, and 83 years of age. Serial sections were made throughout the length of these muscles. Consecutive sections were stained with different methods. To discriminate true spindles from false spindles, light micro...

Fibrillin and elastin networks in extrafusal tissue and muscle spindles of bovine extraocular muscles.

PURPOSE Bovine extraocular rectus muscles were examined to map the distribution of elastin and fibrillin in extrafusal tissue and muscle spindles. METHODS Immunohistochemical techniques and immunolocalization were employed to pin-point the placement of molecules relative to muscle fibers. RESULTS Strands containing elastin and fibrillin surrounded all extrafusal fibers. They also covered th...

Two novel/ancient myosins in mammalian skeletal muscles: MYH14/7b and MYH15 are expressed in extraocular muscles and muscle spindles

The mammalian genome contains three ancient sarcomeric myosin heavy chain (MYH) genes, MYH14/7b, MYH15 and MYH16, in addition to the two well characterized clusters of skeletal and cardiac MYHs. MYH16 is expressed in jaw muscles of carnivores; however the expression pattern of MYH14 and MYH15 is not known. MYH14 and MYH15 orthologues are present in frogs and birds, coding for chicken slow myosi...

Muscle spindles in human extrinsic eye muscles.

the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
