Autonomous nervous system. Consisting of Parasympathetic nervous system and Sympathetic nervous system. Parasympathetic nervous system increases the secretions of digestive tract and Sympathetic system decreases the secretions. Parasympathetic system increases the contractions of smooth muscles and increases the rate and force of peristalsis and Sympathetic system does vise verse.
nucleus
The rate of cell division slows down,controls on growth are restored, and everything returns to normal.
No, the nucleus in a cell is what controls cell division.
The furrow during cleavage is caused by the contraction of a ring of actin and myosin filaments, which are part of the cytoskeleton in the cell. This contraction creates a cleavage furrow that pinches the cell membrane inward, ultimately leading to the division of the cell into two daughter cells. The process is regulated by cellular signaling pathways and is crucial for proper cell division during embryonic development.
When cells are not responding to normal controls over growth and division, they can form tissue masses known as tumors. Tumors can be either benign (not cancerous) or malignant (cancerous).
excess cell growth and division
The cerebrum
The parasympathetic division of the autonomous nervous system sends a message to the digestive system when it's time to produce enzymes.
The central nervous system supplies the body and muscle contraction. Striated muscle (skeletal muscle) contract voluntary with exception of the heart which is striated involuntary smooth muscle.
controls voluntary actions-activities you can choose to do or not to do.

"somatic"
parasympathetic division
The Somatic Division
It controls the activities and reactions in the cells. It is also responsible for cell division.
