Gastrocnemius muscles is the effector.
Afferent Nerve- Sciatic
Efferent Nerve- Sacral 1 & 2 Nerve roots
Receptors- Tendon nociceptors in Tendon of Achilles
Integration centers- Interneurons in the spinal cord
Quadriceps muscle
Flexor Muscles
The brain is not an effector. An effector refers to the glands and muscles doing activity.
The quadriceps group of muscles. Rectus Femoris more specifically.
Errector Pili Muscles
Muscles or glands which carry out the responses
yes brain i s involved in reflex actions as it makes a pathway for sensory neuron to connect with and brain then directs the motor neuron to take a particular action which is given by effector !(muscles)
Motor neurons are able to create a response in effector organs, muscles and glands by sending signals to them.
Somatic reflex
cardiac muscles and smooth muscle
In terms of the nervous system, muscles and glands are given the generic term effector organs. Impulses are picked up from receptors, which then travel to the brain, which sends orders along the motor neurons to these effector organs. In the case of reflex actions, however, the brain is not involved, and the process is done much faster as a result.
There are basically two kinds of neurons- sensory and motor. Motor neurons are responsible for passing on messages from the brain, to the effector muscles, while performing a voluntary action (they also do that for involuntary actions) Sensory neurons on the other hand, detect a stimulus, and pass on the message to the brain, which analyses the information, decides the course of action, and passes on the message back through the motor neuron, to the effector muscles.
the pupil gets smaller because there is an abundance of light present.
