- The middle piece is composed of plasma membrane, AVM, acrosomal vesicle cavity and acrosomal material. 主體部則由細胞質帶圍繞細胞核構成。
- In the mature sperm, acid phosphatase was localized in the percutor organ slightly, but it was massive and compact in the acrosomal tubule. 當精子成熟后酸性磷酸酶均勻分佈在頂體管中;反應產物顆粒比較大;穿孔器部分發現有少量酸性磷酸酶分佈.
- Fertilization is a complex biological process.Motile spermatozoa can fertilize only after they undergo capacitation and acrosomal reaction. 摘要受精是一個複雜的生物學過程,精子必須具備良好的運動功能,同時需經獲能和頂體反應才能實現受精。
