Details

Meiosis describes the cell division of the sex cells; sperm and ovum.  It divides a diploid cell into a haploid one.  46/2 = 23.  Occurs only in the testes and ovaries.

Somatic cells are 2n and genetically identical.  Sex cell are n and genetically unique.  22 autosomes, 1 sex chromosome.

XX = female

XY = male

22 homologous pairs of autosomes

Spermatogenesis is the production of sperm in the testis.  It begins with a somatic cell having 46 chromosomes.

Meiosis involves two cell divisions.  Unequal division, 3 polar bodies, one ova.  The sperm is the smallest of all human cells.  The egg is the largest.

The wrong number of chromosomes leads to defects in many cases.  To diagnose this, use a karyotype.  Down syndrome has 23 autosomes x 22 autosomes = 45 autosomes.

Women release 1 egg a month or 12 eggs a year.  Her ovaries stop working by menopause.  About 400 eggs in a lifetime.  A girl is born with all the eggs she will every have.

A pseudohermaphrodite has XXY for their sex chromosomes.  This leads to a hormonal imbalance.  Kleinfelt’s syndrome.  A Y confers maleness.

Thalamus (reticular activation system – waking center)

Cerebrum – limbic system (emotions), basal ganglia (subcortical nuclei), cerebral cortex

The 12 Pairs of Cranial Nerves

Most are mixed nerves.  Most emerge from the brainstem.

Spinal nerves have 4 types of wires: somatic sensory, visceral sensory, autonomic neurons, somatic motor.

Some Say Marry Money, But My Big Brother Say Business Makes Money

Autonomic motor neurons control the salivary glands.

1 Olfactory – somatic sensory – sense of smell.

2 Optic – somatic sensory – sense of sight.

3 Occulomotor – somatic motor/autonomic motor.  Voluntary control of eye muscles.  Automatic control of pupil diameter.  Pigmented muscle – iris.

4 Trochlear – somatic motor.

5 Trigeminal – somatic sensory/motor. – the most important cranial nerve in dentistry.  Sensation from face and all the teeth.  Mastication.  3 branches.

6 Abducens – somatic motor.  Control lateral rectus.

7  Facial – 3/4.  Taste from tongue.  Contraction of facial muscles.

8 Vestibulocochlear – somatic sensory.  Like 1 and 2.  Sense of hearing and balance.  Cochlea, vestibular apparatus.

9 Glossopharnogeal – means tongue/throat.  Only nerve that is like a spinal nerve.  Has all 4 types of wires.  Taste.  Somatic because one is conscious of it.

10 Vagus –  both.  The largest cranial nerves.  Visceral sensory, somatic motor, autonomic motor.  We don’t feel it.  Internal organs.

11 Accessory – motor.  Larynx, neck and traps muscles.

12  Hypoglossal   -Motor.  Under the tongue.  Propriosection from the tongue.  Injury, can’t move tongue or feel it.

Local anesthetics block nerve conduction in a particular area.

Viral infection of the facial nerve is Bell’s palsy.

Baroreceptors monitor blood pressure.
