What is the function of the superficial sphincter muscle of neck in carnivores?
It tenses and moves the skin on the dorsal and lateral sides of the neck.
What is the characteristic of the subcutaneous layer in large animals?
It is confined to the ventral aspect of the trunk and does not extend beyond the dorsal border of the fold of the flank.
What is the purpose of the synovia bursa in the subcutis?
It prevents damage to soft tissues and skin against bony protuberances.
What is the difference in the subcutaneous fat composition between the horse and the ox?
The horse has yellowish, oily subcutaneous fat, while the ox has white, dry subcutaneous fat.
What is the function of the cutaneous muscle of neck in the ventral aspect of the neck?
It covers the jugular groove and originates from the manubrium of the sternum.
What is the characteristic of the subcutis in the nuchal regions of the horse and the brisket of the ox?
It has substantial accumulations of fat.
What is the difference between the superficial and deep layers of fascia in the head?
The superficial layer is a mask-like covering that continues on the neck, directly beneath the skin, whereas the deep layer extends over the mandible and lies under large superficial blood vessels.
What is the primary function of the fascia in the body?
To form attachments for muscles, facilitate movement of muscles across each other, surround deeper structures, provide routes for passage of blood vessels, lymphatics, and nerves.
What is the thoracolumbar fascia, and where is it located?
The thoracolumbar fascia is a strong, tendinous tissue that covers the thoracic and lumbar regions, attaching to the spinous processes of thoracic, lumbar, and sacral vertebrae, supraspinous ligament, sacral tuberosity, iliac crest, and coxal tuberosity.
What is the buccopharyngeal fascia, and where is it located?
The buccopharyngeal fascia is a deep layer of fascia that partly fuses with the superficial fascia, attaching to the buccal wall and extending between the pterygoid, dorsal border of the mandible, and hyoid apparatus.
What is the temporal fascia, and where is it located?
The temporal fascia is a deep layer of fascia that covers the temporal muscle and attaches to the orbita and zygomatic arch.
What is the function of the cutaneous muscles in the body?
The cutaneous muscles tense and twitch the skin, enabling mimic movements of the lips, nose, and ears, particularly in carnivores.
What is the difference between the superficial and deep fascia of the neck?
The superficial layer of fascia in the neck covers the superficial muscles of the neck, whereas the deep layer covers the thoracic portions of the ventral serrated muscle and encloses the common carotid artery.
What is the endothoracic fascia, and where is it located?
The endothoracic fascia is a deep layer of fascia that lies on the deep surfaces of the muscles of the body wall and blends with the serosal lining of the thoracic cavity.
What is the iliac fascia, and where is it located?
The iliac fascia is a deep layer of fascia that covers the deep lumbar muscles.
What is the function of the superficial sphincter muscles of the neck?
The superficial sphincter muscles of the neck tense the fascia along the ventral aspect of the laryngeal region, at the junction of the head and neck.
Test your knowledge of the fascia and cutaneous muscles, including their structure, function, and relationships with other bodily systems. Learn about the different layers and types of fascia, and how they facilitate movement and provide pathways for blood vessels, nerves, and lymphatics. Understand the importance of fascia in enclosing and supporting various organs and muscles.
