What are the two small swellings that can be found at the dorsal aspect of upper medulla?
hypoglossal trigone and vagal trigone
The Control Mechanisms For Breathing Including Both The Dorsal And Ventral Groups?
Breathing is controlled by a network of neurons located in the brainstem, specifically in the medulla oblongata and pons. The dorsal respiratory group in the medulla primarily controls inspiration, while the ventral respiratory group also in the medulla is involved in both inspiration and expiration. These groups coordinate the rhythmic pattern of breathing by sending signals to the diaphragm and intercostal muscles.
What is the medical term meaning knuckle?
The dorsal aspect of the flexed metacarpophalangeal joint.
What is the four-part muscle on the dorsal aspect of the foot?
extensor digitorum brevis
Do frogs have a dorsal cords?
Yes. all animals that have a an endoskeleton and a backbone will be present with a dorsal nerve cord.
What are the differences between the ventral and dorsal aspects of the human body?
The ventral aspect of the human body refers to the front side, while the dorsal aspect refers to the back side. The ventral side typically contains organs like the heart and stomach, while the dorsal side is where the spinal cord and shoulder blades are located.
What are the differences between the dorsal and plantar aspects of the foot?
The dorsal aspect of the foot is the top part, while the plantar aspect is the bottom part. The dorsal side is where the toes and the top of the foot are located, while the plantar side is where the sole of the foot is. The dorsal side is typically more exposed and has a higher concentration of sensory receptors, while the plantar side is more weight-bearing and has thicker skin.
What are the key differences between the plantar and dorsal aspects of the foot?
The plantar aspect of the foot is the bottom part, while the dorsal aspect is the top part. The plantar side is in contact with the ground and has thicker skin, while the dorsal side is more sensitive and has thinner skin. The plantar side also has a thicker fat pad for cushioning, while the dorsal side has more prominent bones and tendons.
The parasympathetic motor pathways begin in the areas?
Most parasympathetic motor pathways begin in the dorsal aspect of the medulla, in the dorsal motor nucleus of the vagus nerve. Parasympathetic motor pathways also come from the preganglionic cell bodies located in the lateral horn of the spinal cord in the sacral region (pelvic splanchnic nerves). Thus, the description cranio-sacral is often used to describe the origins of the parasympathetic innervation.
What happen If the dorsal respiratory group of neurons in the medulla oblongata were destroyed bilaterally?
If the dorsal respiratory group of neurons in the medulla oblongata were destroyed bilaterally, it would lead to decreased drive for inspiration, resulting in respiratory depression or even respiratory arrest. This group of neurons plays a crucial role in regulating the rhythm and depth of breathing.
What is the back of thigh bone?
The femur or thigh bone is the largest and strongest bone in the body. The dorsal aspect of the bone is also referred to as the posterior aspect of the femur.
What are the differences between the dorsal and plantar aspects of foot anatomy?
The dorsal aspect of the foot refers to the top part, while the plantar aspect refers to the bottom part. The dorsal side typically has more hair and thicker skin, while the plantar side has thicker padding and more sweat glands. Additionally, the dorsal side is more exposed to the environment, while the plantar side bears more weight and pressure when walking.
