Quick Answer: What spinal nerve is responsible for muscles of the anterior forearm and lateral hand?

What region of the brain originates from the embryonic hindbrain?

The layers of the embryonic brain. The telencephalon and diencephalon give rise to the forebrain, while the metencephalon and myelencephalon give rise to the hindbrain.

What type of nerve fibers What controls the skeletal muscles of facial expression?

The facial nerve is the seventh (cranial nerve VII) of the 12, paired cranial nerves. It emerges from the brainstem between the pons and the medulla and controls the muscles of facial expression.

What is the name of a specialized capillaries that secrete cerebrospinal fluid?

The choroid plexus is a complex network of capillaries lined by specialized cells and has various functions. One of the primary functions is to produce cerebrospinal fluid (CSF) via the ependymal cells that line the ventricles of the brain.

Which tract carries sensory information about touch pressure and body movements to the cerebrum?

The dorsal column system (sometimes referred to as the dorsal column–medial lemniscus) and the spinothalamic tract are two major pathways that bring sensory information to the brain (Figure 14.5.1). The sensory pathways in each of these systems are composed of three successive neurons.

What is the function of hindbrain?

Hindbrain, also called rhombencephalon, region of the developing vertebrate brain that is composed of the medulla oblongata, the pons, and the cerebellum. The hindbrain coordinates functions that are fundamental to survival, including respiratory rhythm, motor activity, sleep, and wakefulness.

How does hindbrain develop?

Hindbrain Development

The rhombencephalon divides into the metencephalon and myelencephalon. The metencephalon grows into the cerebellum and pons of the adult brain, and the myelencephalon will become the medulla of the adult brain, containing a large fourth ventricle and posterior choroid plexus in the thin roof.

What nerve is responsible for muscles of the anterior Brachium like the biceps Brachii?

The musculocutaneous nerve innervates the muscles in the anterior compartment of the arm: Biceps brachii.

What produces cerebrospinal fluid?

According to the traditional understanding of cerebrospinal fluid (CSF) physiology, the majority of CSF is produced by the choroid plexus, circulates through the ventricles, the cisterns, and the subarachnoid space to be absorbed into the blood by the arachnoid villi.

Where is CSF reabsorbed?

The CSF from the subarachnoid space is eventually reabsorbed through outpouchings into the superior sagittal sinus (SSS) known as the arachnoid granulations. Arachnoid granulations act as an avenue for CSF reabsorption into the blood circulation through a pressure-dependent gradient.
