Final answer:
The labrum is poorly vascularized and has a limited nerve supply, which has implications for labrum injury.
Step-by-step explanation:
The labrum is poorly vascularized and has a limited nerve supply. This means that the labrum has a reduced blood flow and fewer nerve endings compared to other tissues in the body.
For labrum injury, the lack of vascularization means that it has a reduced capacity for self-healing. Additionally, the limited nerve supply may result in reduced pain and sensation, making it difficult to diagnose and treat labrum injuries.
