In the reflex arc a muscle or gland is considered to be the?
They are effectors as they bring about a response.
The autonomic nervous system and the pituitary gland are controlled by the?
Hypothalamus.
Which gland in the body are also part of the central nervous system?
The hypothalamus and pituitary gland are both located in the CNS.The hypothalamus is part of both the central nervous system and the endocrine system because it sends out nervous impulses and manufactures hormones. The hypothalamus' hormones tell the pituitary gland to either secrete or stop secreting its hormones.
Autonomic nerves innervate what three things?
Smooth muscle Cardiac muscle Gland
What endocrine gland develops from the sympathetic nervous system?
Adrenal medulla
How does effector relate to reflex arc?
An effector is at the end of a reflex arc as it is the muscle or gland that 'does' the reflex. What the effector does is the outcome of the reflex arc.
In the reflex arc a muscle or gland is considered to be the?
They are effectors as they bring about a response.
The structure that brings about response in the nervous system?
The effector such as a muscle or gland brings about response in the nervous system.
Name a structure that receives signals from autonomic nervous system?
Smooth muscle, cardiac muscle, gland
First step in a reflex arc?
A reflex arc involves the following components:The receptor is the part of the neuron (usually a dendrite) that detects a stimulus.The sensory neuron transmits the impulse to the spinal cord.The integration center involves one synapse (monosynaptic reflex arc) or two or more synapses (polysynaptic reflex arc) in the gray matter of the spinal cord.A motor neuron transmits a nerve impulse from the spinal cord to a peripheral region.An effector is a muscle or gland that receives the impulse from the motor neuron. In somatic reflexes, the effector is skeletal muscle. In autonomic (visceral) reflexes, the effector is smooth or cardiac muscle, or a gland.
The efferent division of the peripheral nervous system innervates?
A muscle or a gland. Efferent fibers carry information away from the CNS to innervate tissues that perform functions; such as a gland, a smooth muscle, a skeletal muscle, or cardiac muscle. The antonym to efferent would be afferent.
What division of the autonomic nervous system mediates the reflex release of saliva?
The parasympathetic nervous system stimulates salivary gland secretion, and accelerates peristalsis, so, in keeping with the rest and digest functions, appropriate PNS activity mediates digestion of food and indirectly, the absorption of nutrients. Source: Wikipedia: http://en.wikipedia.org/wiki/Autonomic_nervous_system enteric nervous system is responsible for the pupillary light reflex
What gland directly stimulated by the nervous system to secrete hormones?
adrinal gland stimulates the nervous system
What are the structures and functions of a reflex arc?
A reflex is a rapid, involuntary response to a stimulus such as a hot stove.The reflex arc is the pathway traveled by the nerve impulses during a reflex. Most reflexes are pathways that traverse only the spinal cord.During a spinal reflex, information may be transmitted to the brain, but it is the spinal cord that is responsible. They can happen faster than you can think about it.A reflex arc involves the following components:The receptor is the part of the neuron (usually a dendrite) that detects a stimulus (burn).The sensory neuron transmits the impulse to the spinal cord.The integration center involves one, two or more synapses in the gray matter of the spinal cord.A motor neuron transmits a nerve impulse from the spinal cord to a peripheral region.An effector is a muscle or gland that receives the impulse form the motor neuron (remove the hand). In somatic reflexes, the effector is skeletal muscle. In autonomic reflexes, the effector is smooth or cardiac muscle, or a gland.
What best indicated the pathway that nerve impulses travel in a simple reflex?
A simple reflex travels in this order:StimulusA stimulus (stimuli, plural) is an outside happening that affects the body (i.e., sound, sight, taste, pain). 2. Sensory ReceptionThis is when the body senses the stimulus through receptors located all over the body. Some receptors are clustered to form our major sensory organs (i.e., taste buds on tongue).3. Central Nervous SystemSensory neurons transmit the signal to the CNS (brain and spinal cord) through peripheral nerves that connect from the body's extremities to the CNS.If this simple reflex is part of a simple reflex arc (a stimulus that produces some reflexive response), the brain then sends instructions through a motor neuron to an effector (usually a muscle or gland). This prompts either muscle movement or chemical action.
Which gland is a bridge between the nervous system and hormone system?
The pituitary gland
In the reflex arc the muscle or gland that responds to a motor impulse is called?
Effector. Memory Aid = The Effector really should be called the Effectee, since it's the one getting effected. Its cheesey but helped me memorize it...
