This comprehensive guide will explore the basics of the female torso, including its bones, muscles, and skin. These issues can significantly impact a woman's quality of life, but they are often treatable with the right approach. The breast form, a combination of glandular and fatty tissue forms, is attached to the fascia (a sheathing layer) that is situated over the pectoralis major muscle. It is caused by the buildup of plaque in the coronary arteries supplying the heart, eventually the arteries may become so narrow that not enough blood is able to reach the myocardium, [18] a condition known as myocardial infarction or heart attack, this can cause heart failure or cardiac arrest and eventually death.

The process begins with fertilisation, where an egg released from the ovary of a female is penetrated by sperm. The urethral opening is for the urethra that carries urine from the bladder and the clitoris which contains the most sensitive nerve endings and in humans has no use other than sexual pleasure.Smooth muscle is found within walls of blood vessels and hollow organs such as the stomach or intestines. The brain is placed within the neurocranium, and is formed from the cerebrum, cerebellum and brainstem ( pons and medulla oblongata). One of the most significant differences between male and female anatomy is, of course, the reproductive system.

It then travels to the atrioventricular node which makes the signal slow down slightly allowing the ventricles to fill with blood before pumping it out and starting the cycle over again. With regards to the endocrine system function; hormones produced by the endocrine system act to regulate a wide variety of bodily functions, such as triiodothyronine which regulates metabolism, or estrogen and progesterone which regulate the menstrual cycle. Whilst functionally, the nervous system is considered as two parts; the somatic (SNS) or voluntary nervous system, and the autonomic (ANS) or involuntary nervous system. The specific problem is: Should be cut down more to fit the length of the other systems, and some paragraphs are a bit difficult to read.Female (left) and male (right) adult human bodies photographed in ventral (above) and dorsal (below) perspectives. One way is to group them by their location on the anterior, lateral, and posterior regions of the body, but they can also be classified by anatomical regions (abdominal region, scapular region, pectoral region) or by their placement in relation to the surface (superficial layer, intermediate layer, deep layer). Levator scapulae is innervated by the dorsal scapular nerve (C5) and anterior rami of C3-C4 spinal nerves. Pectoralis major is innervated by the lateral and medial pectoral nerves, two branches of the brachial plexus.

Even if you don’t know the exact muscle placement for all muscles if you know the proportions well, even simplified figures will look accurate.

The internal oblique muscles originate from the anterior two-thirds of the iliac crest, the iliopectineal arch and the thoracolumbar fascia. Interspinales lumborum - originates from the superior aspects of the spinous processes of vertebrae L2-L5 and inserts onto the inferior aspects of the spinous processes of vertebrae L1-L4. Sometimes we get lost while studying about cells and molecules and can’t see the forest for the trees. The pectoralis major muscle helps move the humerus, and the pectoralis minor and the serratus anterior muscles help move the scapula bone.
