Answer:
Endosteum
Explanation:
The hollow region in diaphysis is known as medullary cavity which is filled with the yellow marrow.
<u>The endosteum is the thin vascular membrane of the connective tissue which lines up inner surface of bony tissue which forms medullary cavity of the long bones.</u>
Endosteal surface is reabsorbed usually during the long periods of malnutrition and thus resulting in the less cortical thickness.
Answer:
The answer is B: All the muscle cells innervated by a single motor neurorn.
Explanation:
It is called a motor unit, all muscle fibers that are innervated by a motor neuron cell. A motor neuron cell can establish contact with up to 150 muscle fibrils, which when activated causes their simultaneous contraction, therefore, all the muscle fibers of a motor unit contract and relax at the same time.
Answer:
The left motor cortex
Explanation:
The cerebral cortex, also known as the neocortex, is the outer layer of neural tissue of the brain. The cerebral cortex is involved in diverse functions including perception, memory, thought, and voluntary physical activity. On the other hand, cerebral palsy (CP) refers to a group of disorders that alter the ability to move and maintain balance and posture. CP is caused by damage or abnormal development of the cerebral cortex (i.e., the part of the brain that directs muscle movement). CP can be divided depending on the type of disorder in motor skills into 1-spasticity (muscle tightness that makes movement), 2-dyskinesia (muscle imbalance), and 3-ataxia (muscle incoordination problems). People suffering from dyskinetic CP have problems controlling the movements of their hands and arms. The left motor cortex is known to control the movements of the right side of the body, while the right side of the motor cortex controls the movements of the left side of the body. In consequence, it is expected that a person with CP who has movement problems to control their right arm and hand is affected in the left motor cortex.
This sounds like a UTI, and i would prescribe a probiotic for a yeast infection, not a nasal spray considering nothing is wrong with his sinuses.
