1.primary oocytes 
<span>- diploid (2 complete sets of chromosomes) </span>
<span>- 'formed' from oogonia during the process of oogenesis </span>
<span>* primordial follicles consist of a primary oocyte + a single layer of squamous follicle cells </span>
<span>* primary follicles consist of a primary oocyte + 1/several layers of cuboidal follicle cells </span>

<span>2. secondary oocytes </span>
<span>- haploid (1 complete set of chromosomes) </span>
<span>- developed from the primary oocyte undergoing meiosis I to form a secondary oocyte + a tiny first polar body </span>
<span>* found in the matured Graafian follicle </span>
<span>* begins meiosis II & stops at metaphase II upon ovulation & only continues upon fertilisation</span>

V125BC [204]

The nervous system and the muscle system respond to stimuli to produce motion. The skeletal movements of muscles are mostly voluntary.

Involuntary movements occur in these muscles when the nerve impulse passes from a sensory neuron to a motor neuron via an interneuron in the spinal cord.

<h3>What are Skeletal muscles?</h3>

Skeletal muscles may be defined as the muscles that fasten to your bones and authorize you to achieve a broad range of activities and operations.

Skeletal muscles control the direct movement of a person's will and are hence referred to as voluntary movement. While the spinal cord is associated with both movements directly or indirectly. It is a prolonged, delicate tubelike network liable for holding incoming and outgoing messages through the brain to the rest body.

Therefore, it is well described above.

Chromosomes only exist inside gametes true or false
netineya [11]

The male human has a sperm cell and the female has an egg cell. The cells from the male and female that combine to form a zygote are called gametes. The human sperm and egg cells each contain 23 chromosomes. . A combination of gametes forms a zygote with 46 chromosomes. The type of cell division that produces gametes with half the normal chromosome number is the meiosis. Meiosis is the type of cell division used in sexual reproduction. It will occur in the testes and ovaries.<span>Chromosomes get shuffled when eggs and sperm are made. Though most adult cells contain two sets of chromosomes, sperm and egg cells are different. These special cells have just one chromosome from each pair. Which chromosome they get from each pair is random, making each sperm or egg cell unique. There is also a bit of mixing before the chromosomes are sorted into individual sperm or egg cells. Chromosomes from each pair in a mother or father, respectively, make contact and exchange pieces of DNA, creating hybrid chromosomes. </span>
