Are the first seven pairs of ribs considered false because of their posterior and direct anterior attachments?

the first seven pairs are the only true ribs, because they attach anteriorly to the sternum. unlike the last five whose cartilage combines before the sternum, which makes them false ribs.

Can the pituitary gland function without the hypothalamus?
No, because the hypothalamus manufactures the hormones for the posterior pituitary gland and it sends the instructions for the anterior pituitary gland to produce hormones.
How would you Describe the differences you observe in the type and distribution of hair on the front and back of your forearm?
The skin on the front of the forearm (anterior) has more hair because it has a thicker layer of skin. The forearm (posterior) has less and thinner layers than the anterior, so it has less hair
Why is the serratus anterior in humans called the serratus ventralis in cats?
It's because, unlike humans who stand upright, cats do not have a front, or anterior aspect. So the word anterior is replaced with the word ventral.
Functions of sinuses in humans?
They are present because if the face was solid bone, the anterior portion of the head would weigh more than the posterior part of the head, making it off balance. The air-filled bones weigh less than solid bone, so the head stays balanced on the neck.
What keeps the femur from slipping backward off the tibia?
1. The posterior cruciate ligament (PCL) keeps the femur(thighbone) from slipping off the tibia (shinbone), because it connects to both from the back.
Is the spinal cord posterior to the lungs?
No, the heart is anterior to the spine. Posterior means "behind" therefore the spine is posterior to the heart.
Are the adrenal glands divided in to the anterior lobe and posterior lobe?
No it's not! it's the Pituitary Glands that divided the anterior and posterior lobes and thats because it's connected to the hypothalamus!!!!!!
Ribs numbered 11 and 12 are true ribs because they have no anterior attachments?
False
Why is anterior asynclitism more favourable during normal labor than posterior asynclitism?
Because it can easily rotate
Is the trachea anterior to the spinal cord?
Yes, the trachea is anterior to (in front of) the spinal cord or, in other words, the spinal cord is posterior to (behind) the trachea.ANS2:The previous answer is 90 degrees wrong.The trachea is ventral to the spinal cord. Anterior means towards the head and posterior means towards the tail. Ventral is towards the belly and dorsal is towards the back.
Can the hypothalamus function without the pituitary?
No, because the hypothalamus manufactures the hormones for the posterior pituitary gland and it sends the instructions for the anterior pituitary gland to produce hormones.
Can the pituitary gland function without the hypothalamus?
No, because the hypothalamus manufactures the hormones for the posterior pituitary gland and it sends the instructions for the anterior pituitary gland to produce hormones.
Why are spinal nerves mixed nerves?
Spinal nerves are said to be mixes because their posterior roots contain sensory axons and their anterior roots contain motor axons.
Why middle cerebral artery stroke is more common than anterior cerebral artery or posterior cerebral artery stroke?
because it is in continuity with internal carotid artry, usually embolus lodges there.
Why are there more indirect muscle attachments than direct attachments?
Indirect attachments are more common because of their durability and small size.
How would you Describe the differences you observe in the type and distribution of hair on the front and back of your forearm?
The skin on the front of the forearm (anterior) has more hair because it has a thicker layer of skin. The forearm (posterior) has less and thinner layers than the anterior, so it has less hair
Is the hypothalamus is a gland or not?
The parts that traditionally comprise the hypothalamus are not usually considered as a gland. However, a part of the pituitary gland -- which is a type of gland called an endocrine gland-- is actually just an extension of part of the hypothalamus. So technically, it'd be perfectly reasonable to say that that part of the hypothalamus is also part of an endocrine gland.Glands come in two types: endocrine and exocrine. Endocrine glands secrete chemicals into the bloodstream, whereas exocrine glands secrete chemicals and fluids out of the body.The pituitary gland (also called the hypophysis) is one of the body's major endocrine glands. In fact, it is considered the "master gland" of the endocrine system. The pituitary gland can be divided into parts; two major parts are called the anterior pituitary gland and the posterior pituitary gland. "Anterior" means that part is towards the front of the gland; "posterior" means it is towards the back.Both parts of the pituitary gland, both anterior and posterior, are endocrine glands. But they have very different structures. The structure of the anterior pituitary is reflected in its other name, adenohypophysis; "adeno-" means glandular and refers to the glandular appearance of the anterior pituitary when viewed under a microscope. In contrast, the posterior pituitary is also called the neurohypophysis; "neuro-" refers to the fact that the posterior pituitary resembles tissue of the nervous system when viewed under a microscope.The two major pieces of the pituitary gland have different microscopic appearances because they come from different areas of the body. The anterior pituitary actually develops from an outpouching of the roof of the mouth early in development. In contrast, the posterior pituitary comes from the gradual extension of the hypothalamus, which lies directly on top of the pituitary gland.During development, nerve cells (called neurons) of the hypothalamus send long projections (called axons) to form the posterior pituitary. Once they reach the right spot, they set up shop next to a blood vessel. There they organize themselves so that the ends of their projections (called axon terminals) sit right next to the blood vessel wall. These terminals contain little sacs of hormones that get released into the bloodstream whenever the nerve cell is excited.So yes, it's definitely fair to consider at least a part of the hypothalamus as an endocrine gland.
