Peripheral N (LONGITUDINAL) Notice it's wavy!! P = perineurium SC = schwann cells F = fibroblasts

Anterior (ventral) horn cell D = dendrite A= axons CS = cytoskeleton

Peripheral Nerve ## Footnote MA = myelinated axon EP = epineurium F = fascicle P = perineurial cells S = perineurial septae EN = endoneurium

**Mitochondria** * Mitochondria are surrounded by a double membrane* * Peroxisomes & Lysosomes are surrounded by a SINGLE membrane*

Golgi complex

Trachea SM at the bottom = esophagus

Peripheral Nerve blue circle = myelinated nerve fibers A = axon

Peripheral Nerve ( in vagina) E = epineurium F = fascicle P = perineurium

Developing intramembranous bone

Cardiac M | (intercalated discs, striations, etc.)

Trachea

IV disc

Nucleus

**Lipid droplets** | (non-membranous inclusions)

Thyroid

Long bone

Identify epithelium, CT, and muscle

Anterior (Ventral) horn ## Footnote CB = cell body NS = nissl substance No = nucleolus Ax = axon

Spinal cord, white matter G = glial cells circled area = oligodendroglia

Endoplasmic Reticulum

Compact Bone

Dorsal root ganglion N = neuron Nuc = nucleus No = nucleoli SC = **Satellite cells (**supportive cells )

**High Endothelial Venules (HEVs)** 1. Entry sites for mature lymphocytes Fluid transport from lymph to blood

Thymus- Hassal's corpuscules (enlarged)

**Thymus (cortex)** Top: ERC bottom: T-cell

What region of what organ is this in? What does it secrete? What does the thing it secretes do?

Thymus (medulla) = Hassall's Corpuscules Secrete **Interleukin** for **T-cell maturation**

What kind of cartilage is this?

fibrocartilage | (type 1 & 2 collagen, GPG)

A. Bronchiole B. Resp. Bronchiole C. Alveolar Sac D. Alveolus G. Alveolar Duct

Intrapulmonary Bronchus

Bronchiole

Inactive mammary gland

Active mammary gland

What organ? What cell? What does its secretory granules contain?

Parathyroid Parafollicular Cell (C-Cell) Secretory granules contain Calcitonin

Identify blue and yellow circles

Parathyroid gland Yellow = chief cells (secrete PTH) Blue = oxyphil cells

Rete testis

Efferent ductules

Epididymis

Testis (adult)

Identify each arrow

Vas deferens

Seminal vesicle

Prostate

Ovary 1. Corpus albicans 2. Atretic follicle

Corpus albicans

Asterisk lies in the lumen of what structure?

Corpus luteum
