WebReflexes can be classified in many different ways, but we will examine them as either somatic: involving control of skeletal muscle, or autonomic: involving control of smooth muscle, cardiac muscle, glands etc. Regardless of their classification, all reflexes have 5 basic components: WebGross Anatomy of the Spinal Cord. This information is covered in the assignment and reviewed and built upon in lecture. The spinal cord transmits information between the brain and the body (with the exception of most structures in the head and neck, which have information carried in cranial nerves, covered in unit 3).

WebThe vestibular system is a part of the sophisticated human postural control system [1], normal static stance relies on three sensory inputs: vision, proprioception and vestibular [2]. It is sensitive to two types of information: the position of the head in space and sudden changes in the direction of movement of the head [3]. WebThe short reflex involves the direct stimulation of a postganglionic fiber by the sensory neuron, whereas the long reflex involves integration in the spinal cord or brain. The difference between short and long reflexes is in the involvement of the CNS. confessions of an advertising man pdfdrive

WebA stretch reflex is the contraction of a muscle in response to stretching of muscle spindles, which are receptors that lie in parallel with extrafusal muscle fibers. The reflex is composed of a two-neuron arc. The afferent … WebReflexes are the simplest circuits within the somatic nervous system. A withdrawal reflex from a painful stimulus only requires the sensory fiber that enters the spinal cord and the motor neuron that projects to a muscle. Antagonist and postural muscles can be coordinated with the withdrawal, making the connections more complex. WebReflexes include not only such simple acts as chewing, swallowing, blinking, the knee jerk, and the scratch reflex, but also stepping, standing, and mating. Built up into complex patterns of many coordinated muscular … confessions of an advertising man
