the dense connective tissue is a scar tissue. It doesn't exert forceful contraction like muscle. The muscle as a whole is still functional although the contraction will be weaker.
The muscle is still functional because the connective tissue only replaces the damaged parts of the large muscle.
Because those vital organs are extremely fragile the bones act as a type of barrier between the organs and whatever the body may come in contact with. Bones like the ribs protect your heart. Other organ like the eyes, brain, lungs, and spinal cord are all protected by bones or your skeleton.
Answer:
Myofibrils.
Explanation:
Myofibrils may be defined as the basic unit of muscle cell that are rod like in appearances. The tubular like myocetes or muscle cells are present in the myofibrils.
Myofibrils consists of dark and light bands. The myofibril is the skeletal muscle organelle that actually contracts during the muscle contraction. The myofibril unit is formed during the embryonic development by the myogenesis process.
Thus, the correct answer is option (E).
The opening of channels that let positive ions flow out of the cell (or negative ions flow in) can cause hyperpolarization. Examples: Opening of channels that let
+
K
+
K, start superscript, plus, end superscript out of the cell or
−
Cl
−
C, l, start superscript, minus, end superscript into the cell.
The opening of channels that let positive ions flow into the cell can cause depolarization. Example: Opening of channels that let
+
Na
+
N, a, start superscript, plus, end superscript into the cell.
The opening and closing of these channels may depend on the binding of signaling molecules such as neurotransmitters (ligand-gated ion channels), or on the voltage across the membrane (voltage-gated ion channels).
The client should remove all metal objects (such as piercings, rings, jewelry of any kind) the day of the scan.
