33
Q

Hermaphrodite

A

An individual possessing both male and female reproductive organs. True
hermaphrodites are capable of producing both ova and sperm

34
Q

Heterogametic

A

Producing unlike gametes with respect to the sex chromosome (e.g. male
mammals produce X and Y bearing sperm)

35
Q

Homogametic

A

Producing similar gametes with respect to the sex chromosome (female
mammals produce only X bearing sperm)

36
Q

Intersex

A

An individual showing morphological and anatomical characteristics that lie between
the typical male and female condition; especially relevant to the genitalia

37
Q

Libido

A

Desire to mate

38
Q

Meiosis

A

The two divisions which precede the formation of gametes in which the members of
each chromosome pair separate, and the chromosome number in the resulting daughter cells is
reduced to half the somatic number; as distinguished from ordinary cell division (mitosis)

39
Q

Metamorphosis

A

Change of shape or structure; a transition from one developmental stage to
another

40
Q

Mitosis

A

Cell division involving the duplication of chromosomes, and the division of the
chromosomes by a process of longitudinal splitting. Thus, each of the resultant daughter cells
receives a full complement of the chromosomes existing in the original cell before division.

41
Q

Septum

A

A dividing wall or membrane

42
Q

Spermatocytogenesis

A

The stage of spermatogenesis that involves cell divisions: more
specifically the process by which spermatogonia develop into spermatocytes and later
spermatids.

43
Q

Spermatogenesis

A

The process of formation of sperm which includes both spermatocytogenesis
and spermiogenesis

44
Q

Spermiogenesis

A

The morphological change that spermatids undergo to become spermatozoa.

45
Q

Spermiation

A

The process by which spermatozoa detach from Sertoli cells.

46
Q

Thermoregulation

A

The regulation of temperature by the body.

47
Q

Tumescence

A

A state of being swollen or tumid.

48
Q

Vasectomy

A

Surgical removal of all or part of the vas deferens.

49
Q

Vasoconstriction

A

The narrowing of the diameter of vessels; especially constriction of
arterioles, leading to decreased blood flow in an organ

50
Q

Why do boars have such a high volume of semen

A

Very well developed accessory glands

51
Q

Piece between the head and middle part of sperm

A

Connecting piece

52
Q

Plasma membrane

A

Covers outside head of sperm

53
Q

Two acrosome membranes

A

outer and inner acrosomal membranes

54
Q

Equatorial segment

A

Where acrosome ends on the head

55
Q

post acrosomal region

A

Where the acrosome doesn’t cover

56
Q

Implantation socket

A

Where part of the neck will attach to the head

57
Q

Capitulum

A

Hooks the tail into the head

58
Q

Middle piece

A

Where the mitochondria is, energy for tail movement

59
Q

Principle piece-Nine outer coarse fibers

A

Important for tail shape, fibrous sheath, contains axomeme

60
Q

Order of sperm structure

A

Middle piece, principle piece, end piece

61
Q

Desired motility

A

Forward progressive motility

62
Q

Primary abnormality

A

if the problem happens during spermatogenesis inside the testis (double head)

63
Q

Secondary abnormality

A

Problem happens after the sperm has left the testis

64
Q

Stages of spermatogenesis

A

Spermatocytogenesis (mitosis), meiosis, spermiogenesis (formation of sperm), spermiation (sperm will be released)

65
Q

Spermatogenesis happens inside the

A

Seminiferous tubules

66
Q

When does meiosis 1 happen?

A

At the primary spermatocyte (64)

67
Q

When does meiosis 2 happen?

20 days

69
Q

Meiosis one is at _ days

A

21

70
Q

Meiosis takes _ days

A

77
Q

Golgi phase C

A

Acrosomic vesicle, acrosomic granule, centrioles moving to neck piece

78
Q

Cap phase A

A

Acrosome becomes flat to cover the nucleus, centrioles line up to form neck

79
Q

Cap phase B

A

Tail starts to form, acrosome formed, neck piece formed

80

Cytoplasmic droplet can form from

A

Excess cytoplasm

81
