Answer:
Yes it does.
And could you come help me with my latest question?
Answer: the correct answer is d. all of the above must happen for defecation to occur.
Explanation:
In response to the distention of the rectal wall, the receptors send sensory nerve impulses to the sacral spinal cord. Motor impulses from the cord travel along parasympathetic nerves back to the descending colon, sigmoid colon, rectum, and anus. The resulting contraction of the longitudinal rectal muscles shortens the rectum, thereby increasing the pressure within it. This then opens the internal sphincter.
Answer:
Evolution, mutation, and adaptation
Explanation:
Since different organisms adapt to different environments and receive different mutations, they adapt differently and slowly change. That is why there are different species of birds, just look at the galapagos islands, there are thousands of species of finches that changed to survive on each island. The same could be said for every organism since the early organisms that we evolved from were widespread, some evolved differently than others, leading to different fish, different lizards, different early mammals, and so on. That is why humans look different than dogs or cats, we evolved best to our environment so we could survive.
The central nervous system (CNS) and effector organs receive messages from receptors through the nerve cells, respectively.
<h3>What do neuron and muscle cells have in common?</h3>
- Tissues are made up of both nerve and muscle cells. Both mitochondria and endoplasmic reticulum are found in muscle and nerve cells. The body's operations are coordinated through the cooperation of muscle and nerve cells.
- Neurons, a type of nerve cell, and muscle cells are significantly distinct from one another. While nerve cells transmit signals from receptor cells to either glandular cells or muscle cells, or both, in order to move the body, muscle cells (myocytes) contract to cause movement.
- The synapse is the point at which a nerve cell can communicate with another cell or muscle cell. The space between the pre-and postsynaptic cell membranes is known as the synaptic cleft.
The function of muscle cells:
The same genetic material can be used to correctly fill in the first blank, and to contract can be used to correctly fill in the second blank.
The genetic material is present in all of the body's cells, including blood, muscle, neuron, and cardiac cells. Cell differentiation causes them to specialize into different types of cells.
Muscle cells' purpose is to contract, which aids in movement and mobility. Skeletal muscles aid in movement and smooth muscles support the operation of interior organs like the uterus, whose contractions aid in childbirth.
