Which descending tract is involved in reflex movements of the head in response to visual and auditory stimuli?
The tectospinal tract is involved in reflex movements of the head in response to visual and auditory stimuli. It originates in the superior colliculus of the midbrain and carries signals for reflexive head and neck movements in response to sensory input.
What tract might be damaged if tremors or jerky movements occurred?
train tract
What are 2 types of movements produced by contractions of the muscularis externa?
The two types of movements produced by contractions of the muscularis externa are peristalsis, which is a coordinated contraction and relaxation of circular and longitudinal muscles to propel food along the digestive tract, and segmentation, which involves the mixing and churning of food within a specific region of the digestive tract for digestion and absorption.
What is The tract that carries sensations from muscle spindles to the CNS is the?
The tract that carries sensations from muscle spindles to the central nervous system is the dorsal spinocerebellar tract. This tract conveys proprioceptive information from muscles to the cerebellum for coordination and balance.
What reflex test is used to detect corticospinal tract damage?
The Hoffmann reflex test is commonly used to detect corticospinal tract damage. This test involves tapping the middle or ring finger and observing for an involuntary contraction of the thumb and index finger. An abnormal or exaggerated response may indicate damage to the corticospinal tract.
Is corticospinal tract an indirect descending tract?
No, the corticospinal tract is a direct descending pathway that transmits motor signals from the cerebral cortex to the spinal cord. It is involved in the control of voluntary movements.
What is lateral corticospinal tract?
Lateral corticospinal tract is the part of pyramidal tract that consists of crossed pyramidal fibres. So, it's also called as "crossed pyramidal tract".as for anterior corticospinal tract, it consists of uncrossed pyramidal fibres.
What are the two important ways in which the GI tract works?
Gastrointestinal tract have digestive secretions to digest the food and peristaltic movements to propel the food forwards.
What causes sulfur smelling bowel movements?
Bacteria in the intestional tract.
What tract is damaged if tremors or jerky movements are observed?
If tremors or jerky movements are observed, the cerebellum may be damaged. The cerebellum is responsible for coordinating movement, so damage to this area can result in issues with smooth and coordinated muscle movements. Additionally, damage to the basal ganglia can also cause tremors or jerky movements.
How do urinary tract infection bacteria affect the body's immune response?
Urinary tract infection bacteria can trigger the body's immune response, leading to inflammation and activation of immune cells to fight the infection. This response can cause symptoms such as pain, fever, and increased urination.
Which fiber tract carries impulses from the cerebrum to lower CNS areas?
The corticospinal tract carries impulses from the cerebrum to lower CNS areas, primarily to control voluntary movements throughout the body. It is involved in motor function and helps in coordinating muscle movements.
