The cytoplasm is a fluid substance that fills every living cell which is enclosed by the cell membrane. This substance is mainly composed of water and proteins.
The functions that take place within the eukaryotic cytoplasm are diverse:
- Location for most metabolic pathways. Except for the metabolic pahtways in cell nucleus and cytoplasmatic organelles, all metabolic functions (e.g., synthesis of biomolecules, growth, etc) occur in the cytoplasm. The cytoplasm contain enzymes (i.e., proteins) to carry out different chemical reactions.
- Location for organelles that house many of the metabolic pathways for the cell. For example, the synthesis of ATP (the energy coin of the cells) is carried out in the mitochondria, which are organelles found in the cytoplasm.
- Location for the cytoskeleton that gives integrity to the cell. The cytoplasm contains all of the three types of filaments of the cytoskeleton (i.e., microtubules, actin filaments, and intermediate filaments) which provides structural support to the cells.
On the other hand, in plant cells, the cell wall is located outside the cell membrane.

Golgi tendon organ manages muscles and prevents injury by monitoring the rate of muscle contraction.
What is the Golgi tendon organ? What is its primary function?
Sensory organs called Golgi tendon organs (GTOs) are found in the tendon next to the myotendinous junction. The Golgi tendon organ, which is located close to the point where a tendon joins a muscle, is a sensory ending that resembles a tree and is encased in a spindle-shaped connective tissue capsule.
The Golgi tendon organ is the sensory organ that determines how much tension the muscle is exerting when someone lifts weights. The Golgi tendon organ will prevent the muscle from producing any force (by a reflex arc) if there is excessive muscle tension, preventing you from harming yourself. Together, these monitor muscle length via the muscle spindles.

Apocrine sweat glands are most affected by the hormonal changes that occur during puberty.
What is puberty ?
Between childhood and adulthood, puberty is a time of rapid growth, the emergence of secondary sexual traits, the attainment of fertility, and significant psychological changes. Although the order in which pubertal changes occur is fairly predictable, their exact time varies greatly.
At puberty, sex hormones stimulate the apocrine sweat glands, which then begin to work. In the groin and axilla, they are linked to hair follicles. The thick, protein-rich substance has no smell at first but may acquire one after coming into contact with germs.
