Muscles E

Front

What do all muscle tissue develop from

Back

develop from embryonic myoblasts from the mesoderm

Front

What does multinucleate skeletal muscle cells form

Back

form by fusion of many myoblasts

Front

What does growth factor in muscle stimulates

Back

stimulates clustering of ACh receptors at neuromuscular junctions

Front

What two muscle myoblasts do not fuse, but develop gap junctions

Back

cardiac and smooth muscle

Front

When does cardiac muscle cells begin pumping

Back

start pumping when embryo is 3 weeks old

Front

In the regeneration of muscle what does myoblast-like skeletal muscle cells have

Back

Myoblast-like skeletal muscle satellite cells have limited regenerative ability

Front

In the regeneration of muscle what can cardiomyocytes do

Back

Cardiomyocytes can divide at modest rate, but injured heart muscle is mostly replaced by connective tissue

Front

When does smooth muscle regenerate

Back

regenerates throughout life

Front

What kinds of muscles can lengthen and thicken in growing child and in adults leads to hypertrophy

Back

cardiac and skeletal muscle

Front

What does muscular development in infants reflect

Back

reflects neuromuscular coordination

Development occurs head to toe, and proximal to distal

A baby can lift its head before it is able to walk
