Study Notes
Week 7 Integumentary System
- The skin is the largest organ, comprising approximately 16% of body weight.
- The skin consists of three main layers: epidermis, dermis, and hypodermis.
Epidermis
- Made of closely packed epithelial cells (keratinocytes)
- Contains melanin (pigment production)
- Contains keratin (skin rigidity)
- Consists of five layers: stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale.
Keratinocytes
- Primary cell type (90% of epidermal cells)
- Forms a barrier against environmental damage
- Protects against heat, UV radiation, water loss, and pathogens.
- Aids in wound healing.
Dermis
- Two main layers: papillary and reticular layers.
- Papillary layer: highly vascularized areolar tissue, containing capillaries, lymphatic vessels, and sensory neurons, nourishing the epidermis.
- Reticular layer: dense irregular connective tissue, containing collagen and elastic fibers; provides strength and flexibility and houses sensory receptors and blood vessels.
Hypodermis
- Separates skin from deeper structures.
- Contains adipose tissue, providing insulation, cushioning, and storing energy reserves.
Skin Color and Pigmentation
- Factors affecting skin color include genetic programming, UV response, and melanin production.
- Carotene is an orange-yellow pigment.
- Medical conditions like albinism can affect skin color.
Week 13 Sexual System
Female Reproductive System
Vulva
- Consists of mons pubis, labia majora, labia minora, and vestibule.
- Mons pubis: fat pad over pubic bone, covered in pubic hair.
- Labia majora: hair-covered skin folds extending from mons pubis to perineal raphe.
- Labia minora: thinner, more pigmented folds medial to labia majora.
- Vestibule: region between labia minora.
Female Internal Organs
- Ovaries: almond-sized gonads (2-3 cm), located near fimbriae.
- Uterus: muscular organ (5 cm × 7 cm) with three regions (fundus, body, cervix).
- Vagina: muscular canal (10 cm).
- Breast anatomy: Contains mammary glands (modified sweat glands), nipple, and areola.
Male Reproductive System
Penis and Testes
- Testes: spherical gonads (4-5 cm) producing sperm and androgens.
- Scrotum: muscular sack regulating temperature for sperm production.
Functionalities:
- Sperm travels through the ductus deferens during ejaculation.
- Scrotum function: Maintains optimal temperature for sperm production, adapting to environmental temperature changes.
