Ansa

The Ansa is a term used in the field of anatomy to refer to a loop-like structure. It is derived from the Latin word for "handle". In the human body, there are several structures referred to as ansae, including the Ansa cervicalis, Ansa lenticularis, and Ansa sacralis.

Ansa Cervicalis

The Ansa cervicalis is a loop of nerves located in the cervical region of the neck. It is part of the peripheral nervous system and provides motor innervation to several muscles in the neck, including the sternohyoid, sternothyroid, and omohyoid muscles.

Ansa Lenticularis

The Ansa lenticularis is a part of the brain involved in the regulation of movement. It is a component of the basal ganglia, a group of nuclei located deep within the cerebral hemispheres. The ansa lenticularis carries signals from the globus pallidus, a part of the basal ganglia, to various other parts of the brain.

Ansa Sacralis

The Ansa sacralis is a nerve loop in the sacral region of the spinal cord. It is part of the parasympathetic nervous system and is involved in the regulation of various bodily functions, including the functioning of the bladder and bowel.
