What reflex is important in maintaining balance?

What reflex is important in maintaining balance?

C. any nerve serving a muscle that produces a movement at a joint innervates the joint, but not the skin over the joint. D. any nerve serving a muscle that produces a movement at a joint does innervate the skin over the joint, but not the joint.

Which of the following reflexes is particularly important in maintaining balance and often accompanies the flexor or withdrawal reflex in weight bearing limbs?

The crossed-extensor reflex often accompanies the flexor reflex in weight-bearing limbs and is particularly important in maintaining balance.

Which of the following reflexes serves in maintaining posture?

the stretch reflex and muscle contraction. Note: By sending command to the motor neurons, the brain set a muscle’s length. The stretch reflex makes sure the muscle stay at that length. The stretch reflex is therefore important for maintaining muscle tone and upright posture.

Which of the following cranial nerves means the wander?

The name “vagus” comes from the Latin term for “wandering.” This is because the vagus nerve wanders from the brain into organs in the neck, chest, and abdomen. It is also known as the 10th cranial nerve or cranial nerve X.

How autonomic reflexes help maintain homeostasis?

The autonomic nervous system helps maintain homeostasis through the involuntary activity of autonomic reflexes. these reflexes enable the ANS to control visceral function: smoother muscle contractions ( or relaxation), cardiac muscle contractions, or stimulation of inhibition of secretion by glands.

What are the 4 types of reflexes?

In our discussion we will examine four major reflexes that are integrated within the spinal cord: the stretch reflex, the Golgi tendon reflex, the withdrawal reflex and the crossed extensor reflex.

What reflexes include all those reflexes that involve stimulation of skeletal muscles?

Autonomic / Somatic reflexes include all those reflexes that involve stimulation of skeletal muscles.

Which of the following is a superficial reflex?

superficial reflex any withdrawal reflex elicited by noxious or tactile stimulation of the skin, cornea, or mucous membrane, including the corneal, pharyngeal, and cremasteric reflexes. swallowing reflex palatal reflex. tendon reflex contraction of a muscle caused by percussion of its tendon.

What is Moro reflex?

Moro or “startle” reflex A dramatic reflex during these first few weeks is the Moro reflex. If your baby’s head shifts position abruptly or falls backward–or if he is startled by something loud or abrupt–he will extend his arms and legs and neck and then rapidly bring his arms together. He may even cry loudly.

What branch es of the vagus nerve go to the pharynx and larynx?

The vagus nerve arises from the fourth branchial arch; this arch is also responsible for the development of the pharyngeal and laryngeal muscles, the laryngeal cartilages, the aortic arch, and subclavian artery.

How are reflexes regulated?

A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.

How nervous system maintains homeostasis?

Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis. Through its receptors, the nervous system keeps us in touch with our environment, both external and internal.
