Answer:
Squamous epithelia.
Explanation:
The cells of the squamous epithelial are wider than their height. These cells are found in the lining of esophagus, mouth and alveoli of the lungs.
These cells helps to pass the material by the process of diffusion. These are the thinnest tissue and also plays an important role of filtration.
Thus, the correct answer is option (A).
Answer: Poor motor control impairs;
--> the smoothness and
--> accuracy of joint movement.
Explanation:
The peripheral nervous system controls the motor system in vertebrates. The motor system also consists of two parts which includes:
--> The somatic nervous system and
--> The autonomic nervous system.
The motor neurones that carry instructions to voluntary muscles, that is, those muscles that we can control consciously, makes up the SOMATIC NERVOUS SYSTEM. These motor neurons are part of some of the spinal and cranial nerves. Their cell bodies are in the central nervous system; their nerve fibres extend all the way to the skeletal muscles
Impulses that speed along these fibres stimulate( excite) the muscles to being about the appropriate movements.
The somatic nervous system controls all skeletal movements. These movements include:
--> all voluntary actions like clapping ( which we can choose to do or not to do), and
--> control of the body equilibrium
Poor muscle control can occur due to injury, illness, or inherited disorder. An individual with poor muscle control is at a higher risk of joint pain and injury because of the damage to the motor neurones that innervates the skeletal muscles attached to joints. This is turn will lead to a decrease in the smoothness and accuracy of joint movement.
The target heart rate zone is the range of exercise intensity that allows you to stress your cardiorespiratory system for optimal benefit without overloading the system.
The target heart rate of an individual refers to the heartbeat range during exercise and is measured as a percentage. The resting heart rate is calculated by checking the pulse beat for one minute. It normally ranges between 60-100 beats/minute. The target heart rate is 220 subtracted by the age of an individual. For example, the target heart rate for a 27-year-old would be 220-27= 193 beats/minute. Therefore, at a 50% exertion level, the target heart rate must be 50% of the maximum value, that is, 97 beats/minute.
