Quiz 3 lecture material Flashcards
Main purpose of sperm
transfer genetic material from the male to the female oocyte
Genetic material in the sperm is stored in the
nucleus
Most important part of the sperm
nucleus-where genetic information is stored
What in the sperm tail makes it move
mitochondria provide energy to the microtubules (axoneme) which move in the tail
Sliding of microtubule doublets does what
gives the sperm tail movement
Motility of sperm refers to
how it moves
should move forward
Morphology of the sperm refers to
how it looks
Types of morphology abnormality
Primary
Secondary
Primary Abnormality
happens during the generation of sperm
-Example- double head
Secondary abnormality
happens later after development, produced normally but something else goes wrong
-Example- coiled tail
What type of abnormality is a severed head
can be secondary or primary
Crater Defect is what type of abnormality
primary
Tapered head is what type of abnormality
primary
Ruffled acrosome is what type of abnormality
Primary
Knobbed Acrosome is what type of abnormality
Primary
Coiled tail is what type of abnormality
Secondary
Double midpiece is what type of abnormality
Primary
Folded tail is what type of abnormality
Primary or secondary
Detached head with a normal tail semi attached
Secondary
Job of Sertoli cells
nursing cell
support spermatogenesis
Stages of spermatogenesis
Spermatocytogenesis (mitosis)
Meiosis
Spermiogenesis (formation of sperm)
Spermiation
Spermatocytogenesis
Spermatocyte production
increase in number
Meiosis
makes the sperm cell haploid for the proper number of chromosomes for offspring
Spermiogenesis
changes the shape of the cell from a circle to sperm shaped
