Where are the receptor sights located for kinesthetic sense?
It depends on what the receptor cells are for. If they are for vision, they are located in the retina of the eye. If they are for hearing, they are located in the organ of Corti, and so on and so forth.
What holes are in the surface of the dendrites or certain cells of the muscles and glands that are shaped only to fit certain neurotransmitters?
receptor sites
Which body system is responsible for responding to the environment?
The nervous system comprises the body's total response mechanism. It receives external information, sends that info to the brain for processing, and sends messages from the brain about appropriate response to the effector muscles and glands.
What is the opening that is controlled by the muscles of the iris?
The opening that is controlled by the muscles of the iris is called the pupil. The iris is responsible for adjusting the size of the pupil in response to different lighting conditions.
Three differences between sensory neurone and motor neurone?
# Motor neurones have cell bodies inside the Central Nervous System (CNS) whilst in sensory neurones the cell body is located outside of the CNS # Motor neurones transmit impulses from the CNS to the effector which brings about a response to the situation, sensory neurones transmit impulses from to the CNS from the receptor. # Sensory neurones transmit impulses as a result of external stimuli such as pressure, light, temperature etc. Motor neurone transmit impulses passed along the CNS to the effector.

Receptor found in muscles provide information about length or change in length of skeletal muscles?
muscle spindle
What are holes in the surface of the dendrites or certain cells of the muscles and glands that are shaped to fit only certain neurotransmitters?
Neurotransmitter receptor sites on ligand-gated ion pores.
What drug that interferes with the binding of signal molecules to receptor proteins in the heart muscles?
the beta blocker.
What is the response caused by spinal cord interpreting an impulse from sensory receptor?
The only response by the spinal cord is not an interpretation but a reflex. A sensory impulse comes in and at the cord a reflexive arc occurs taking information to muscles or glands. The brain does the interpretation. You touch a hot stove and that info goes to the spinal cord which causes a reflexive action where the muscles move the hand away. All that happens before the brain gets an "incident report".
Muscles or glands that bring about a coordinated response?
Effectors is the term used for glands or muscles that result in a coordinated response. Receptors are what receive stimuli from the outside environment.
Jhindra's twitching facial muscles were a response to the stress of moving to a new country the doctor said?
Jhindra's twitching facial muscles were a response to the stress of moving to a new country the doctor said it was a somatic response.
What holes are in the surface of the dendrites or certain cells of the muscles and glands that are shaped only to fit certain neurotransmitters?
receptor sites
When a person is performing intense physical exercise and begins to feel fatigue and a burning pain in the muscles the response of the muscles is to synthesize more?
When a person is performing intense physical exercise and begins to feel fatigue and a burning pain in the muscles the response of the muscles is to synthesize more lactate or lactic acid.
What muscles in your body move on their own?
In humans smooth muscles are controlled by the autonomous nervous system. Smooth muscle is found in blood vessels, the digestive tract, the iris and skin. These muscles move or contract in response to automatic signals, e.g. the presence of food in the stomach or bright light in the eyes. Cardiac muscle also contracts automatically, controlled by special groups of pacemaker cells in the heart.
What is called the red light reflex?
The red light reflex (startle response) is a withdrawal response in the abdominal muscles in which the body curves in on itself in response to distress.
Is there any connection between adrenaline and nervousness?
Adrenaline is a "fight or flight" hormone associated with the sympathetic nervous system in the human body. This means that if you need to do alot of physical exertion or think fast, the body diverts resources to the relevant areas. This is usually an automatic survival response when the brain reckons it's entering a situation of danger, so is preparing itself; e.g. pumps more blood around to oxygenate muscles, liberate more energy from stores, puts muscles on edge for quick use, etc. A situation of nervousness is interpreted by the body as danger, so the above system is activated, releasing adrenaline, giving the characteristic fast heart, twitchy muscles, and an inability to relax. In today's modern society, it's an evolutionary survival mechanism which was important in more dangerous times gone by, but can be useful sometimes, like when you do encounter a genuinely dangerous situation.
