(9/25/25) formative assessment assignment: chapter 6 the muscular system part 1 (suggested ... 4 of 16 smooth muscle smooth muscle has no striations and is involuntary, which means that we cannot (1 ) control it. found mainly in the walls of hollow (tubelike) visceral organs such as the stomach, urinary bladder, and respiratory passages, smooth muscle propels substances along a pathway. think of smooth muscle as visceral, (2 ). and involuntary smooth muscle fibers are spindle - shaped, uninucleate, and surrounded by scant endomysium (see table 6 - 1). they are arranged in layers, and most often there are two such layers, one running (3 ) and the other longitudinally (figure 6 - 2a). as the two layers alternately contract and relax, they change the size and shape of the organ. moving food through the digestive tract and emptying the bowels and (4 ) are examples of “housekeeping” activities normally handled by smooth muscles. smooth muscle contraction is slow and sustained. to use a running analogy, if skeletal muscle is like a sprinter, who runs fast but tires quickly, then (5 ) muscle is like a marathoner, who runs more slowly but keeps up the pace for many miles. o 1. bladder 2 smooth 3 consciously 4 nonstriated 5 circularly o 1. circularly 2 bladder 3. smooth 4 consciously 5 nonstriated o 1 nonstriated 2 circularly 3 bladder 4 smooth 5 consciously o 1. consciously 2 nonstriated 3 circularly 4. bladder 5 smooth o 1 smooth 2 consciously 3 nonstriated 4 circularly 5 bladder

Explanation:

Smooth muscle is involuntary, meaning we can't consciously control it. It's non - striated and visceral. Layers are circular and longitudinal. Emptying the bladder is a function. Comparing to skeletal muscle, smooth muscle is like a marathoner.

Answer:

1. consciously 2. nonstriated 3. circularly 4. bladder 5. smooth
