EXPLANATION
Functional Anatomy & Histology of Female Genitalia: Ovaries, Oviducts (Peg Cells) & Cervix (Sialomucin)
- Cervical Mucus Dynamics During Estrus:
- Under the dominant influence of high follicular estrogen, the bovine cervix secretes Sialomucin—a low-viscosity, watery, thin mucus.
- Privileged Sperm Pathways: Sialomucin is produced deep within the basal cervical crypts. Its parallel oriented macromolecular micelles create 'privileged pathways' through which progressively motile spermatozoa can easily swim forward into the uterus, while non-motile sperm, bacteria, and debris are trapped in high-viscosity Sulfomucin flowing along the central cervical canal.
Correct option: (1) Sialomucin
