muscular musculature

Na vertebrates, muscular musculature ekewa ndị na-esonụ iche iche:

• Somatic, nwere ihe n'ime na-akpụ uru nke aka na ụkwụ. Nke a na-agụnye skeletal muscle.
• Visceral (akụkụ nke viscera). Ọ bụ ezigbo onye na gbasara obi uru.

The muscular usoro nke mmadụ

Skeletal uru striated na aka ike. Ha na-mmasị ka ọkpụkpụ na na-cylindrical a eriri ogologo nke 1-10 cm.

Onye ọ bụla muscle eriri - bụ undifferentiated cytoplasm (sarcoplasm) na ihe cores mere ndokwa na mpụta. Mpụta na-agụnye differentiated striated myofibrils. Ọ daputara na mpụta nke uzo n'ọbọ (sarcolemma), nke bụ collagen fibrils. A obere ìgwè nke akwara gbara endomysium; isi muscle ogige bụ n'ùkwù n'ùkwù akwara, mere n'ime ime peremizy; onye ọ bụla muscle gbara gburugburu n'ihu peremiziem. Akwara na connective anụ ahụ na-aga n'ihu onye ọ bụla ọzọ na ibe. The dum muscle na-nchọ na a n'ọbọ-akpọ fascia. Skeletal usoro-agụnye mọzụlụ, ọ bụla nke na jikọọ na irighiri akwara ọbara arịa na na-penetrated ha.

Musculo-skeletal usoro

Ahụ mmadụ nwere banyere 400 striated uru, nke na-ebelata n'okpuru akara nke Central ụjọ usoro.

Musculo-skeletal usoro-agụnye mọzụlụ, ọkpụkpụ, akwara, njikọ, akwara na cartilage na-eme ka fọrọ nke nta ka 75% nke ahu aro. Nke a usoro na-enye ahụ mmadụ a na-udi, enye ohere ya na-eguzo na-eje ije.
